How to sharpen scissors at home

Sharpening scissors yourself is easier than it seems

A skillful housewife will be able to give a second wind to outdated things. If the scissors stop cutting, they crumple the material, and there is no man’s hand in the house, you should not immediately run to a specialist. This step-by-step instruction will show you how to sharpen any scissors at home.

• What is the problem?
• Types of scissors. Individual approach
• Available means

What is the problem?

The first thing people pay attention to is why did the blades lose their sharpness? The reason may be not only wear of the blades, but also the fastening itself. Inspect the instrument carefully. If the blades do not fit snugly together, there is a noticeable gap between them, or there is other play, fix that specific problem first.

There are two types of fastening of such products - with a bolt and with a rivet. In the first case, you should tighten the bolt using a screwdriver. In the second, the scissors should be secured on a strong, flat surface, a nail should be installed in place of the rivet and a couple of blows should be made with a hammer. Thus, the rivet plug will be flattened and will resume its previous durability.

The scissors are twisted in an open form. This is necessary to regulate the pressure and not overdo it.

Types of scissors. Individual approach

The defect has been corrected, but the scissors still do not cut. In this case, determine the type of product. Each of them has its own sharpening method.

Regular scissors

They are intended exclusively for everyday use. Therefore, simple sharpening methods are suitable for such a tool, without fear of damaging the thick blade of the tool.

Using Sandpaper:

It is important that the entire surface is worked during the cutting-grinding process.
• take an abrasive with a grain size from 160 to 250;
• point the paper with the rough surface outward;
• make 20 longitudinal cuts, making sure that the entire surface of the blades is involved in the work (remember the base).

After this, wipe the scissors with damp material to remove any remaining crumbs. This method is suitable for moderately dull blades.

Using a whetstone

Modern whetstones (or whetstones) have two working sides - fine-grained and coarse. If the edge of the blades is very dull, sharpening should be done in two stages - first on a rough surface, then on a fine-grained surface.

To ensure high-quality sharpening of scissors using a whetstone, disassemble the tool itself. This is done to sharpen each blade separately.

Preparation for the process:

• position the whetstone, limiting its mobility and sliding;
• Cover the stone with liquid soap base or water.

When everything is ready for sharpening, take one half of the scissors. Turn the inside of it towards the whetstone (this is the flat side, without an edge). Find the correct line of contact with the whetstone. Do not change the sharpening angle or move away from the existing angle of the tool .

The following actions:

• take the handle of the blade, pressing it over the entire surface onto the sharpening stone (don’t forget about the base);

• run the blade over the rough surface 10 times (the same on the fine-grained side).

After the inner side is processed, proceed to sharpening the outer blade. Use both surfaces of the whetstone. The fine-grained part will ultimately give the necessary smoothness.

After finishing the process, wipe the blades with a damp cloth to avoid burrs. Now all that remains is to connect the halves of the product and check its sharpness.

Manicure

When sharpening, move the tool in one direction

To sharpen such scissors at home, you can use a diamond wheel. Determine the degree of blade wear. Pay attention to the cutting surface. If there is a lot of wear, rings or spots (the size of a millimeter) appear on it. If there are a lot of them and their diameter exceeds 2 mm, then the product urgently needs high-quality sharpening.

An ordinary diamond needle file can also be used for sharpening. It will appear in everyday life more often than a diamond wheel. To sharpen scissors with this tool, place the file on a stable surface and, pressing the edge of the blade tightly, drag along the rough surface in one direction.

As a last resort, resort to sharpening your nail scissors using a whetstone. The method of action is similar to the previous ones.

Do not forget to wipe the product after sharpening. Nail scissors require more attention to detail.

Hairdressers

This type of blade is sharpened with a coarse stone. However, such scissors are a master's tool. And therefore, in order to achieve a good result, it is worth using another interesting method.

Purchase a special medium-grain diamond paste. Take a smooth wooden beam, slightly longer than the length of the scissors. Rub the sides with a moderate layer of paste. This method will help you sharpen your hairdressing scissors perfectly. Over time, this procedure is repeated as the diamond layer wears out.

Garden

Compared to the others, this is a massive tool. Sharpening it requires attention and effort.

Use a grinding wheel

Grinding wheel. If you don’t have it on your farm, it doesn’t matter, there are other ways

Rules of use:

• remember: the circle should rotate only from the blade, not vice versa;

• when sharpening, do not change the angle, as in previous cases;

• during the process, the blade will heat up, so you should take care of an accessible container with cold water;

• To prevent the circle from driving onto the adjacent blade, it is recommended to untwist the tool into two halves before work.

Sharpening with a file

Select the required file size. Separate the halves of the scissors. If in previous methods the blade sharpening was not secured, then in this case the action is the opposite. Secure the blade with the sharp side facing up. Hold the file with both hands and repeat sliding movements along the surface to be treated. Maintain the same angle along the length of the blade. 10-15 repetitions are enough.

Zigzag scissors

Despite the clearly different edge of the blades, sharpening such a product is easy. The standard method using sandpaper is suitable here. Use the fine grain option. After folding the paper in half, cut it into small strips, using the entire length of the blades. Do up to 20 repetitions, then test the sharpness on the fabric.

Available means

If you don’t have sandpaper or a sharpening stone at hand, don’t put off sharpening your scissors. Use available tools.

Don't have any of the above on hand? Take a simple bottle and “cut” it. The scissors will be sharpened.

Sharpening method using foil

Foil is widely used in almost every home; it is not difficult to find. Take a small sheet of aluminum foil and fold it into small pieces. Repeat the action until you get a sheet 10 cm long. Now start sharpening, making cuts in the sheet. For best results, use a similar method in three approaches.

Gypsy needle

The method is original, simple and accessible. Secure the needle at the very base of the cutting surface (the place where the two halves of the scissors are held together). Close the blades and push the needle towards the sharp tips until you feel resistance. Use caution when using this method. Do not allow the needle to slip out. Movements should be slow and sliding.

Let your husband rest: I’m sharing the secret of how to sharpen scissors in one minute

Do you agree that scissors are perhaps the most important tool in the household? In any case, I use them almost daily. But they, like knives, need periodic sharpening. When my scissors became dull, I asked my husband to sharpen them so they would become sharp again. But he never found the time for this. Then I couldn’t stand it and sharpened the scissors myself. It turned out that it is not so difficult.

Want to know what it takes? I am pleased to share with you the secret of my trick.

What does it take to sharpen scissors?

To perform this procedure you will need a minimum of tools. You need to take:

• sheet of foil;
• scissors;
• a piece of paper (to check the result).

Then you can proceed directly to sharpening.

Instructions

This is the trick I want to tell you about for sharpening scissors. Just follow the instructions below:

• Take a piece of foil and fold it in half first, and then several more times until it becomes thick and dense enough. You can fold the sheet up to 10 times.

• Take scissors and cut a thick piece of foil into strips. The more there are, the better. In this way, the process of sharpening dull blades will take place. That is, the scissors will self-sharpen on a thick sheet of foil. It's very simple and fast.

After this, my scissors became sharper, almost the same as when I bought them.

In this simple way, I not only sharpened the tool, but also wiped my husband’s nose. I managed to solve the problem myself. By the way, you can sharpen scissors countless times this way. As soon as they become dull, you can immediately take out the foil to make the blades sharp again.

I liked the sharpening process so much that I didn’t have enough scissors. As a result, I helped my mother and friends make instruments sharp. Use this method too.

How to sharpen scissors at home - sharpening methods

Scissors are one of the most useful tools in the household. But the blades become dull over time, and the owner is forced to look for a sharpener. If you don’t have a machine at home, use folk advice. We will tell you how to sharpen scissors at home, without having special equipment on hand. You will learn about ways to sharpen cutting tools and receive many valuable recommendations.

Why don't scissors cut?

Absolutely everything gets dull: metal scissors, manicure and tailor's tools. If you work in a hairdresser or tailor, the easiest way is to go to a professional workshop. But first you need to understand the causes of the problem. The scissors can get jammed if a nail or cuticle gets caught in the middle - the problem can be solved by simply removing the blockage. But other reasons are more common.

If you use a cutting tool, be prepared for the blades to loosen over time—the scissors will not cut, but will pinch the fabric. An increased gap indicates that it is time to tighten the screw. If the hair is not cut and the paper is not cut, the fact indicates that the tool has lost its former sharpness. All you have to do is sharpen your scissors at home and forget about short-term inconveniences.

Scissors sharpening angle

Preparatory work

It all comes down to the selection of materials that will be useful in the process of sharpening edges. If you're working with a knife, a sharpening stone will suffice, but with scissors you have many more options. And these decisions are not always related to diamond stones.

You can use the following as a sharpener:

1. Sandpaper (prefer highly abrasive sandpaper).
2. Diamond circle.
3. Sharpening bar.
4. Glass jar (sounds weird, but it works).
5. Aluminum foil (sold in any hypermarket, it won’t hurt your wallet too much).
6. A needle or pin (a multifunctional thing, as you will soon see).

Important: Do not rush to throw away your manicure kit if the scissors become dull. A new one costs a lot, it’s not rational.

Some tools have a curved profile (this is typical for manicure tools), so they are not easy to work with. Sharpening ordinary scissors at home is simple, quick, and affordable, but before that, let’s compare the methods listed above in table format. We will evaluate on a five-point scale.

Comparative analysis of sharpening methods

Technology	Speed	Efficiency	Price
Emery	4	3	4
Grindstone	5	4	2
Diamond wheel	5	5	1
Glass jar	1	2	5
Needle	1	3	5
Foil	2	3	5

How to sharpen scissors: sharpening methods

To the materials listed above, it is worth adding a file, or even better, a needle file. In some cases, this tool replaces a coarse-grained block, and the presence of a handle makes it convenient to use. At this point, you should complete the list of available tools and begin directly to work.

Proceed like this:

1. Soak a cotton pad in the alcohol solution.
2. Wipe the curly scissors (or equivalent) with alcohol to remove any dirt.
3. Examine the condition of the mounting bolt.
4. Armed with a screwdriver, tighten the fastening if necessary.
5. If the screw is held on the rivet, use a hammer (if there is a bolt, use pliers).
6. When defects are detected (chips, nicks, rust), everything becomes more complicated. It is better to take the tool to a workshop, where they will repair it using a machine.

Important: The screw must be tightened with great care. If the mechanism stalls, you will not be able to correct the situation - all you have to do is throw the thing away.

How to determine the appropriate sharpening method? It all depends on the type of scissors you will be working with. We will focus on the most common technologies, focusing on hairdressing and manicure tools. We will act mainly manually.

Foil and sandpaper

Regular foil, used by housewives for baking food in the oven, will do. Fold kitchen foil to create 6 layers. It will have to be cut with dull scissors. Be patient - you should like the end result.

Sandpaper is used in a similar way. Fold the sheet in half (with the abrasive layer facing out) and start cutting. Sandpaper slightly sharpens the cutting edges, but this is a temporary effect. Be mentally prepared to re-process or look for other solutions.

To make your scissors sharper, fold the foil into several layers.

Metal sponge

Every housewife will have a metal sponge in her kitchen, designed to remove heavily soiled dishes. Using this device you can sharpen nail scissors.

The technology is already familiar to you from the previous section - start cutting. There is only one downside - the sponge will leave a lot of metal debris. We recommend using a trash can and working on it.

It is worth remembering that a metal sponge can leave scratches

Jar

A small jar or elongated bottle is used. Place a glass container between the blades and start sharpening. The jar cannot be seriously damaged in this way, but the scratches will remain. Keep this in mind when working - you will have to throw away the jar.

Choose thick glass so that it does not crack during operation

How to sharpen nail scissors

To sharpen thin nail scissors, the fastest and most affordable way at home is a diamond wheel, which is used by professionals. The diamond attachment is good in every sense, but the owner must have the skills to use this tool.

Let's give some valuable advice:

• act carefully, avoid strong pressure;
• sharpen the edges at the same angle, do not change it in the process;
• set the circle to minimum speed;
• straighten the edge from the tip of the point;
• move the tool smoothly.

Note: The scissors do not sharpen perfectly on the first try. If you are not satisfied with the result, run the circle again - this way you will bring the tool to perfection.

A good replacement for a circle (if you don’t have one) is a diamond needle file. Practice the movements so that they become the same. Work your way traditionally from the tips of the edges towards the rings. Arm yourself with fine- and coarse-grained needle files. At the initial stage, the edges are processed with coarse abrasive; during finishing, fine grain is added.

Needle against dull blades

If you need to sharpen haircut scissors or an item from a manicure kit, you can use a needle or pin. You will spend a lot of time, but the characteristics of the tool will improve for a short time.

You can use a screwdriver instead of a needle

Hairdressing scissors - use a file

If you cut people's hair and use thinning shears, the situation becomes more complicated. Low density materials (strands of hair) cannot be cut by a blunt instrument. To sharpen your haircut scissors, you will have to find an ordinary file. Some physical effort will be required.

Algorithm of actions:

1. Clean the instrument from dirt with an alcohol solution.
2. Spread the blades of the scissors as far apart as possible so that they are oriented upward.
3. Fix the rings with your hand and maintain a constant angle of inclination.
4. Start grinding the inner edges while holding the tool at a 60° angle.
5. Guide the file towards you, smoothly moving it from the tips of the blades towards the rings.

Important: Sharpening is carried out in one direction. Back-and-forth movements will damage the instrument.

Sharpening with a whetstone

Special device

We are talking about sharpeners sold everywhere in hardware stores. Let us immediately note that such devices are powerless against curved nail scissors - the ends must be straight.

Pay attention to the special holes - this is where the cutting edges should be inserted. You should move in the usual direction - towards the fastening bolt. 5-7 repetitions are enough for the instrument to regain its former sharpness.

Useful tips

There are things that are strictly not recommended if you do not want to damage the instrument. Scissors are an item that serves its owner for years. But the operation must be correct.

The tips are:

1. Remember that garden scissors are used to trim branches, and manicure scissors are used to trim nails. Improper use of the tool is fraught with negative consequences.
2. Boiling an instrument to disinfect is bad. Regular “water procedures” lead to corrosion. Use antiseptics if you want to get rid of bacteria.
3. Every six months, lubricate the mounting assembly with oil. Castor, olive and even vegetable oil will do. 2 drops are enough to prevent corrosion and ensure smooth movement of the backlash.
4. If you want to properly sharpen the scissors yourself, you should not disassemble the mounting unit. There are parts in this tool that cannot be reinstalled.
5. The entire cutting edge is not sharpened - stick to the factory sharpening angle. Total grinding will damage the blade. Incorrect tilt is also bad, remember this.

After sharpening, be sure to remove burrs using paper or napkins.

Thinning scissors are not ideally sharpened; it is better to take them to a master. But other types of tools are quite amenable to manual processing. After studying our article, act boldly but carefully. This is better than throwing away a thing that has not fully exhausted its resource.

How can you sharpen old scissors?

Useful tipsLifehacks

In the modern world, it is no longer customary to sharpen scissors; usually they are simply thrown away and new ones are bought. But there are often cases when it’s simply a pity to throw away old scissors, especially those that were made during the Soviet Union. In this article we will talk about possible ways to sharpen old scissors at home using improvised means.

Grindstone

The sharpening stone can be in the form of a bar or a circle, but for us this is not fundamentally important, the main thing is that the stone has a fine grain, since large grains will only harm and dull the scissors even more, after which they can simply be thrown away.

The technique for sharpening old scissors using a whetstone is as follows:

• We place a piece of rags on the table so that the sharpening stone does not scratch the surface of the table and does not slip;
• Moisten the whetstone with water and place it on a rag;
• If possible, it is better to disassemble the scissors into two parts for ease of sharpening;
• Look at the angle at which the blade was initially sharpened; we need to sharpen it at the same angle and it is highly undesirable to change it.
• We lean the blade of the scissors with a sharpened angle against the stone, maintaining the desired slope, and with light pressure we move the blade along the stone in the direction away from us.

This kind of sharpening requires experience; the first time you probably won’t be able to accurately hold the angle and sharpen the entire plane of the blade at the same time. This sharpening method is the fastest and most effective of all the ones listed below.

Important! Do not check the degree of sharpness of the scissors with your finger, this is dangerous. To check the quality of sharpening, take a piece of synthetic material and try to cut it. It is more difficult to cut synthetic fabric than natural fabric and only well-sharpened scissors can do it.

Also check the uniformity of sharpening, try cutting a piece of fabric with different parts of the blade, from the very edge near the handle to the very tip. If the scissors are not sharpened evenly, then the base of the blade will cut well, but the tip of the blade will simply crush the material, or vice versa. The section of the blade that jams the material needs additional sharpening.

Using Sandpaper

Using sandpaper to sharpen scissors is essentially a simplified version of sharpening with a whetstone. The quality of sharpening is of course worse than after a stone, but quite acceptable. To work, you need sandpaper with abrasive grits of 150-200, that is, very fine. There are several different techniques you can use for sharpening.

• The scissors are disassembled into two parts, a cloth is placed on the edge of the table and sandpaper is placed on top of it. Next, sharpen each blade in the same way as using a stone.
• The second method is less convenient, but is also sometimes used. In this case, the scissors are placed on the table and sandpaper is rubbed along the blades. The disadvantage of this method is that it is almost impossible to control the sharpening angle, so they usually take a wooden block and wrap it with sandpaper to maintain the angle.
• The third method is passive sharpening. To do this, fold the sandpaper in two with the working side facing out and simply cut off small strips from it. During the cutting process, the blade is sharpened.

Important! When sharpening scissors with a stone, sandpaper or file, always work only on the outer side of the blade, which has a factory sharpening slope. The back of the blade must be straight so that the surfaces of the two blades meet tightly. If you process it from the inside, then you can throw away the scissors after that.

Sharpening scissors with a file

This method cannot be called fast; it requires special skills, precise work and the presence of a special tool. To sharpen scissors with a file, you need tabletop grinders, in which you need to fix the scissors so that the blade is horizontal with the sharp side up and the front side facing you. Then, using a fine file, they sharpen it at the factory angle, accurately observing the slope.

You can do without fixing the scissors in cleats. In this case, we hold the file in our hand and sharpen the scissors in the same way as on a whetstone. Here, too, you need experience and precise observance of the inclination of the blade.

Sharpening with improvised means

In this chapter we will look at the most unusual, but no less effective ways to quickly sharpen old scissors using everything that can be on hand in every home.

• Using a paper clip. There is probably a paper clip in every home, but for sharpening it is important that the paper clip be purely metal, without an additional decorative layer of plastic or rubber. Next, unbend the paper clip, pick up the scissors and open them completely. Place the paperclip across the blade at the very base of the scissors and begin to squeeze the scissors while holding the paperclip with your hands. Under the pressure of the closing scissors, the paperclip will be pushed from the base to the tip of the blade. Repeat this procedure until you get the result. It is important to hold the paperclip perpendicular to the blades so that during the compression process it does not get caught between the blades.
• Using foil. For such sharpening, you need to use foil, which is used for baking dishes in the oven; candy foil will not work. Take a piece of foil and fold it several times so that it is difficult to cut. It is better to roll a sheet of foil into a tube and then cut off 50 mm pieces with scissors. This is how the blade is sharpened.

• Metal hedgehog for washing dishes. This is a sponge that is made of small wires randomly twisted together. To sharpen it, you need to cut pieces from this hedgehog with blunt scissors in the same way as you did with foil or sandpaper. True, after such sharpening there will be nothing left of the kitchen hedgehog.

• Screwdriver or nail. The technique for performing this sharpening is the same as using a paper clip. It is important here that the screwdriver does not have any additional chrome plating on it. It is preferable to use a regular nail, but a screwdriver is easier to hold.
• Glass. Oddly enough, the method of using glass for sharpening is very effective. The sharpening technique is no different from sharpening with a screwdriver or a nail, only in this case a glass bottle with a narrow neck is used, which is inserted between the blades and squeezed, pushing the bottle out. But it's best to use a piece of regular window glass with raw edges. The scissors are opened wide, leaned against the edge of the glass and begin to squeeze, trying to cut. The blade will slide along the sharp edge of the glass and sharpen.

Important! When using the glass or bottle sharpening method, you must first protect yourself using gloves and glasses. You also need to remember that when sharpening on glass, small glass fragments will appear, so do it over a newspaper to carefully remove everything later.

Now you have at your disposal a lot of proven methods for sharpening ordinary scissors and there is no longer any need to take them to the workshop for sharpening; you can sharpen old scissors at home with your own hands.

Sharpening scissors at home

Scissors can be revived at home using a sharpening stone, sandpaper, foil, steel wool, needle or awl. Improper sharpening of hairdressing tools at home can result in damage to the metal structure. It is better to take professional instruments to workshops, where they will be sharpened on a special machine with cleaning and grinding.

Many people solve the problem of poorly cutting scissors by recycling them and buying new ones. The method is not always justified, since Chinese goods will not last long, and a high-quality tool costs a lot. The best option is to sharpen the scissors at home.

About the frequency of events

The answer to the question of how often you need to sharpen depends not only on the purpose of the tool. The frequency depends on the following criteria:

• manufacturer (quality);
• initial sharpening;
• terms of Use;
• Providing proper care.

If you use scissors for their intended purpose, do not overload them, and take proper care of them, the hairdressing and manicure tools will remain sharp for up to 2 years. Scissors for metal, as well as for fabric, are sharpened once every few months. If the device is rarely used, a single treatment per year is sufficient.

Stage one - preparation

Stationery and hairdressing models are easier to process than other types. But before starting the process, establish the exact reason for the poor performance of the tool. Often the problem is not associated with dull cutting surfaces, but with a weakened fastening axis, stop heel, or rivet at the junction of the blades.

When starting to sharpen, many do not even inspect the cutting edge.

There are often nicks, material residues, and rust on the edge. If you get rid of dirt with alcohol or a solvent, the product will cut well again, but even sharpening is powerless against rust.

When you have tightened the mechanisms and they “sit” tightly, cleaned them, but the device still fails, you will have to sharpen the scissors. Prepare a work surface, gloves so as not to injure your hands, and a sharpening tool.

Attention ! Modern products are equipped with a Ring Lock mechanism - a reinforced design that has replaced traditional screws and rivets. Ensures a tight fit of the canvases and their long service life.

Devices for home use

At home, a sharpening stone or an electric machine is used as a sharpener. Mechanisms differ in operating principle and in the final result - using the machine will give the best result.

Application of whetstone whetstone

On one side it has a fine-grained texture, on the other - coarse-grained. Start with the rough side (second).

A whetstone or water stone is a block or circle of abrasive material

You can sharpen scissors in this way:

1. Place a cloth under the stone.
2. Moisten the whetstone with water.
3. If they are held on a bolt, disassemble them; if they are held on a rivet, move the cutting edges as far apart as possible.
4. Do not change the inclination of the factory sharpening!
5. Make sure that the plane of the blade tilts away from you while working.
6. Make sure that the chamfer is parallel to the block.
7. When sharpening, move the blades slowly to one side.
8. After working on a coarse-grained texture, repeat the same steps on a fine-grained one.

To check, use a piece of fabric or a sheet of paper: if it is cut well by weight, then it will be cut on the table surface as well.

Electric machine

The machine is equipped with devices for fixing tools at a certain angle, as well as moving along the sanding wheel.

Similar mechanisms are common among craftsmen who make knives, as well as in specialized workshops. But you can buy the instrument for home.

part of a sharpening machine - an emery wheel with different inclination and grain size

An ordinary electric sharpener, which requires a support table, can cope with sharpening cutting blades, since each edge must be secured by hand, both taking into account the angle of inclination and also taking into account the length.

To properly sharpen scissors on a machine:

1. Set the guide at an angle.
2. The circle rotates towards the blade.
3. For final sharpening, pass the blades 2-3 times.

There is no need to straighten products after sharpening on the machine.

Important ! The sharpening angle of office scissors is 60°, for cutting harder substances – 70-75°. A lower angle indicates increased sharpness of the blades. But reducing the angle provokes premature wear of the devices. To avoid damaging the product, do not change the factory angle.

Handy tools at home

Manicure and tailor's scissors are sharpened using simple components that are found in every home. With each manual device, a number of nuances are observed.

Sandpaper

The sandpaper is folded in half, with the rubbing side on top. Next, simply cut the sandpaper into strips (15–20 strips are enough).

This way any blades can be sharpened on an abrasive surface.

Advice ! For quick sharpening and good results, use GOST sandpaper from 10-N or 20-N.

Needle or awl

Sharpening scissors with a needle, pin or awl is easy. Place the needle between the cutting edges as close to the bonding area as possible. Make active movements that simulate the cutting process. The needle will move towards the ends of the edges, thereby sharpening them. The method will remove irregularities that prevent the blades from working properly.

Aluminum foil

The method is convenient because it uses ordinary foil for baking. Sharpening occurs on a similar principle as with sandpaper: food foil is folded in several layers and finely cut into small strips 20–30 cm long.

Quickly sharpen with foil

Like other technologies, the use of foil is called home sharpening. But in reality, this is only a superficial adjustment of the cutting plate with a temporary effect.

By the way, foil can be used to clean silver.

Special cases

Depending on the purpose of cutting tools, the method of sharpening them is selected. Before restoring blades, read useful information that will not only help extend the life of the tool, but also not harm it.

Hairdressing and thinning salons

Professional hair cutting products are sharpened in specialized salons for servicing hairdressing tools. In such places there is special equipment with a laser sight. Keep in mind that hairdressing equipment is designed for long-term use, so steel with a high degree of hardening is used for their production.

Manicure scissors and tongs

Cuticle nippers are sharpened with a file. The process takes several steps:

1. Check the play in the articulated joint.
2. If present, remove it by tapping the axis with a hammer.
3. Cleaning from dirt with sandpaper.
4. In the unclamped state, the inner sides are ground with a file.
5. Separately, sharpen the tips of the nippers with the same file.
6. Squeeze the tweezers and grind the outer edges.

A laser is used to restore manicure devices. Without its use it is difficult to ensure proper quality. Therefore, if the tool does not cut well, it is better to replace it.

Sharpening of manicure tools is carried out using special equipment:

• check the play, remove it with a hammer, if necessary;
• the axle is lubricated;
• for work take a diamond file;
• sharpen each blade separately from base to tip;
• at the same time, the sharpening angle remains unchanged.

Tailor's scissors

Fabric tools are sharpened carefully, otherwise they can ruin the expensive material. Home sharpening is carried out by cutting foil, plastic bottles, and the necks of glass bottles.

It is better if a specialist does this

They check the quality of the work done this way: allow thin cuts of fabric to hang. If the cut area is smooth, the fabric is not compressed or caught by the edges, then the tool is sharpened with high quality.

Do I need to sharpen office scissors?

If we are talking about a cheap product of questionable quality, it is better to throw them away. Sharpening in this case will not bring much benefit. Therefore, only high-quality devices can be processed. At home, use any of the proposed methods. When a problem arises with products with bent ends, it will be more difficult to repair it yourself. Contact a specialist.

On a note! Sharpening knives for meat grinders is possible at home.

Metal scissors

For the manufacture of such tools, durable steel with a hardness of 60 HRC is used. The sharpening angle is 75o. Despite the significant difference from other devices, sharpening takes no more than half an hour. Manufacturers insist on professional service, but men often prefer home methods.

There are 2 ways: fast and high-quality. The first is relevant when there is an urgent need to use the tool. They resort to fine-grain sandpaper and a needle (select a thicker device). The result is short-term and ineffective.

The second method requires more time, but the result is more productive. Use an abrasive in the form of a file and a vice:

• the instrument must be disassembled;
• one part is fixed in a vice so that the surface to be processed is on top and the tip “looks away from you”;
• the file removes excess on the blades, grinding them to a perfectly smooth edge (movement “pull away”);
• the file is moved in one direction slowly;
• Similar actions are carried out with the second part.

Don't collect it right away. Proceed to work after treating the metal with an anti-corrosion compound.

Surgical scissors

There are at least 4 types of surgical scissors. They are made from high-quality steel; the tool requires precise sharpening. The accuracy of the cut depends on this. When working with a medical instrument, the master takes into account the following nuances:

• angle: standard value is 3°, but it may deviate from the standards. Leave the determination of the angle to the experts;
• the direction of movement of the sharpener - the contact of the cutting knives depends on this;
• type of sharpening equipment - taking into account the structure and type of metal, select the appropriate equipment.

Sharpening is preceded by the stage of diagnosing the condition of the surgical instrument: the degree of wear, condition and closure of the blades are revealed.

Sharpening scissors like a pro

Scissors have different appearances depending on their purpose. Some of them may be made entirely of metal, while others have handles made of plastic. Their blades are connected using rivets or screws. But the most important thing is that the sharpening angle of the blades is different. For scissors designed for cutting paper, it is close to 90 degrees, for household or tailor's scissors - 70 degrees ±10 degrees, for hairdressers - 60 degrees ±15 degrees, etc.

The sharpening angle is set at the factory and cannot be changed while using the scissors.
This is where the skill of sharpening a given cutting tool along the entire length of the blade lies to a greater extent. Let's look at how professionals sharpen scissors and, in general, how they are kept in perfect working condition.

Sharpening scissors

We begin the inspection with the internal surfaces of the blades. Slight roughness and even shallow scratches are not only acceptable here, but also necessary: ​​due to them, the material being cut does not slide along the blades and is processed efficiently.

If there are deep scratches and burrs left after sharpening, the inner surface of the blades can be slightly corrected on a flat or round fine-grit sharpening stone, after sprinkling them with water. There is no need to show special diligence in this regard.

The most crucial moment is sharpening the cutting edges of the scissors blades.
Here, professionalism lies in maintaining the initial sharpening angle, which must remain constant from the beginning to the end of the cutting edge, that is, one cannot do without the “hardness” of the hand. It is necessary to securely fasten the blade with the cutting edge up in a carpenter's vice.

As a sharpening tool, you can use a file with a fine notch or a set of sharpening stones of different grain sizes. You can also use a round stone. Of course, sharpening should be carried out using “wet” technology.

During sharpening, it is necessary to regularly wipe the blade with a soft cloth and check the degree of sharpness of the cutting edge.
An experienced craftsman can easily do this by running his finger along the edge. A less experienced specialist will need to check the sharpness by cutting the fabric. It will be considered high quality if the scissors easily cut the fabric anywhere on the blade, including the ends, without crushing the material or “chewing” it.

Care of scissors

Sometimes even a well-sharpened tool does not cut well. In this case, you should check the tightness of the screw holding the blades together. If it is insufficient, then a gap forms between the cutting edges, into which the material gets clogged and the cutting process stops or becomes of poor quality.

This defect can be easily eliminated: tighten (but not overtighten!) the screw, and the problem will disappear. For high-quality operation of the scissors, it will not hurt to occasionally lubricate this screw and the adjacent lever areas with a drop of machine oil.

Another problem during cutting may be the appearance of a gap at the ends of the blades. In this case, the cutting edges will not close and the material at the end of the scissors will not be cut. It is not difficult to eliminate such a defect: the problem is in special plastic or metal stops located between the rings, which should be slightly ground off with a file.

How to sharpen scissors: rules, step-by-step instructions

Scissors, like any other metal tool, become dull over time. Therefore, many people often wonder how to make sharp scissors at home without resorting to the help of craftsmen with professional equipment. We'll talk about this later.

Rules for sharpening scissors

To make scissors sharp correctly, you should follow a number of simple rules, which are presented below:

1. You need to sharpen in the direction away from you, without moving back and forth. This movement will destroy the blade.
2. Sharpening should be done at the factory angle. Each scissor has an average angle of 60 or 70 degrees and this angle cannot be changed.
3. After work, the sharpened tool must be sanded using sandpaper, regardless of the sharpening method used. Sandpaper will allow you to consolidate the result and eliminate minor defects that make the blade of poor quality.

Attention! To sharpen manicure tools, you should use only fine-grained sandpaper. Otherwise, the product may be damaged.

How can you sharpen scissors?

You can sharpen any type of scissors with a whetstone (stone), foil, sandpaper and a file. At the same time, it is easiest to give the original appearance to stationery and hairdressing models than to manicure ones. Special measures are applied to sharpening manicures, for example, using a small block with a small abrasive material or sandpaper with a fine-grained structure.

Interestingly, you can find any tool in a hardware or construction store. It is important to remember that, despite the bluntness of the blades of the scissors, you can still cut yourself. Therefore, when working, you should use protective fabric gloves and perform all actions carefully.

How to sharpen scissors: step-by-step instructions

You can sharpen with foil as follows:

• Take ordinary aluminum foil and fold it in half 6-8 times;
• Cut it as many times as necessary until it is completely sharpened.

It’s easy to find out the result: each time it becomes easier to perform the action.

You can make a tool sharp using sandpaper by performing the following steps:

• Use sandpaper with 150 or 200 grit.
• Rub the scissors firmly on the paper so that it does not slide on the table.

Reference! You can also cut it, just like foil, as many times as needed to give the tool a sharp edge. Usually this is 20-25 actions. In much the same way, you can make sharp scissors with a metal sponge for washing dishes.

Sharpening with a whetstone is more difficult, but more effective than previous sharpening methods. To do this, you will need to take a block and place it on a cloth to prevent the table from slipping or damaging. Then lightly moisten the stone and open the tool to its limits. Then, in a direction away from you, begin sharpening each half of the tool, without changing the factory inclination. The most important thing is to do the work extremely carefully so as not to harm yourself and the product.

The scissors must go completely across the stone, otherwise the sharpening result will be negative: they will cut the fabric and paper unevenly. It is better to start sharpening with a coarse-grained surface of the stone and finish with a fine-grained one. Manicure tools are sharpened using the same technology. However, to sharpen them, a small stone and a fine-grained structure are used.

In general, you can sharpen such a tool for cutting paper or manicure yourself, without resorting to the services of craftsmen with professional equipment. It is enough to remember the above recommendations and instructions for action.

Functions and features of using zigzag scissors for fabric

0 1 667 views Tailor's scissors

Zigzag fabric scissors occupy a special position in the world of tailoring tools. They are universal because they can be used for both cutting and trimming fabric. They are decorative because they produce beautiful, non-fraying cuts and original cut fabric decorations. They can be used not only for fabric, but also for other materials when doing needlework.

Zigzag scissors for a tailor: general characteristics and functions

Zigzag tailor's scissors can be called differently: scalloped, serrated, curly, nozhnicy zig zag. These names reflect the specific appearance of the tool and the results of processing fabric.

Zigzag scissors are universal in use (photo: aurora.ru)

The cutting edge of the scissors is equipped with teeth sharpened along the outer edge. Because of them, the tool is sometimes also called grooved scissors. After processing a cut of fabric with them, an edge is obtained in the form of a wave or curly teeth, which is why they are called patterned scissors.

The name of the scissors is due to the presence of teeth on the blades (photo: cs5.livemaster.ru)

Why are serrated scissors used when sewing?

• trim the edge of the fabric so that it does not fray;
• make decorative cuts on thick fabric;
• give an original look to cut out elements to decorate the product.

These scissors can cut fabrics of different densities, leather, and even cardboard when creating decorative jewelry. But if you plan to use them only for sewing, you will have to stop cutting paper so that they do not become dull prematurely.

Scissors are slightly heavier than universal cutters due to the fact that they have a thicker and wider blade. This is necessary because when the cutting surfaces are compressed, the zigzags fit into each other. Thanks to the tight closure of the teeth during cutting, creasing of the fabric is eliminated, an even jagged cut is formed and threads do not fall off.

Overview of types and models

Among the curly scissors, the leading models in the ratings are German (Scissor), Taiwanese (Aurora), Finnish (Fiskars), and Japanese (KAI). They are valued for the high quality of the material from which they are made.

Serrated scissors come in different sizes. Their length ranges from 21 to 24 cm. For different models, the distance between the teeth varies from 3 to 7 mm. Some manufacturers produce sets of shaped scissors, from which a seamstress can choose the right tool for cutting thick or light fabric, finishing an edge, or cutting out a decorative ornament.

Curly scissors come in different sizes and differ in the arrangement of teeth (photo: i0.photo.2gis.com)

The characteristics of some models of zigzag scissors are shown in the table below.

Model	Characteristic
Fiskars Classic	Suitable for rough fabrics. The extended lower blade supports the fabric while cutting. The distance between the blades is adjusted with a screw
AU 489A	Prevents material from shedding. Features comfortable nylon handles
KAI N5350	Allows you to avoid overcasting the edges of the fabric. Have plastic shock-resistant handles
Konig 159	Model with self-sharpening blades. Suitable for cutting lining fabrics and decorative edge finishing on materials that tend to fray a little
Tiger A-85	Cuts thick and thin fabrics. Make decorative edge processing
Premax 1162 / 8″	Can be used for cutting fabrics of different densities and for decorative edge processing

How to choose

The choice of serrated scissors must be approached responsibly, because a good, convenient tool can replace many other types of tools, and sometimes even a sewing machine. When choosing, you should never focus only on the manufacturer or cost. Low-priced scissors from a less popular brand may work better than famous models.

It is very important that the handle of the scissors fits comfortably in the palm of your hand and does not rub the skin. Left-handers can choose specialized models with mirrored blades. If the scissors are large, they may move hard. It is necessary to choose models with an adjusting screw, which will help loosen the stroke and significantly extend the life of the scissors.

Scissors with teeth should fit comfortably in your hand when working (photo: img10.360buyimg.com)

There is a wide selection of serrated scissors for cutting fabric available online. But when choosing your first scissors, it is preferable to go to a company store to check the tool in person. There you can test different models (hold them in your hands and feel the comfort of the handle).

Why test scissors in a store:

• check progress;
• try cutting on scraps of fabric of different densities;
• evaluate the feel of the handle material and the weight of the tool.

A leisurely selection with trial cutting of the shreds will allow you to immediately detect a manufacturing defect in the tool and any other technical inconsistencies. This testing will eliminate dissatisfaction with the purchased scissors and will guarantee the pleasure of using them in tailoring work.

How to use

Most often, fabric scissors are used for cutting out pieces and trimming edges, but only for fabrics that do not fray too much. They are good for cutting felt, drape, cashmere, cloth, felt products. Details are clear and look neat.

Using curly scissors, you can create original jewelry (photo: ae01.alicdn.com)

Scissors with teeth are also used for thin fabrics, so that during the first fitting the edges of the product do not fray too much. When cutting such fabric, the teeth on the blades of the scissors will prevent fraying.

When sewing dense cotton fabrics, using a zigzag model of cutting scissors will allow you to do without further processing of the edges with an overlocker. To strengthen the edge more securely, you can additionally lay a straight machine stitch along it. But if the product is washed often, the edges will still gradually crumble.

Other ways to use zigzag scissors:

• when decoratively processing cuts - the use of curly scissors for felt, drape, eco-leather and other dense fabrics gives the back of the product a neat, beautiful look;
• when duplicating parts - if you cut a part from adhesive interlining or dublerin, and then duplicate it from the base material, then when ironing, the relief cuts will not appear on the front side;
• when connecting round and semicircular cut parts - thanks to the teeth, they fit well in relation to each other.

Scissors are indispensable for needlework. With their help, you can cut out original details and decorations from fabric and other materials.

When purchasing scissors, you need to test them on scraps of fabric of different thicknesses (photo: ua.charivna-mit.westcom.net.ua)

In order for the scissors to serve for a long time and not break, you need to adjust the stroke of the blades using a screw and, if necessary, lubricate it with a drop of sewing machine oil. After finishing work, they should be wiped with a dry, clean cloth.

At home, scallop scissors are almost impossible to sharpen efficiently. They should be sharpened along the plane of the outer edge in relation to each zigzag.

Therefore, dull scissors can only be sharpened in a workshop equipped with special equipment.

Reviews

Rimma: “I bought Aurora wavy edge scissors from Aliexpress.” They work great to keep delicate fabrics from fraying. They are convenient because you can adjust the blade tension with a screw.”

Daniil: “I tried many models, and finally chose Fiskars Classic serrated scissors from the Valdberis online store. Cool model, they cut the fabric clearly and don’t crease.”

Marina: “I work with Tiger A-85 scissors, which I read about on the Internet. Very nice, weighty and well sharpened. The fabric does not tear, the fibers do not break. She cut both thin silk and thick suiting fabric.”

Are your scissors dull?

Do you need to quickly sharpen scissors at home, but don’t have special tools? Available means that can be found in any apartment will do. With their help, sharpening can be done in a matter of minutes. True, the result will not be very durable, but it will be possible to cut “here and now.”

It is better not to experiment with home sharpening methods that involve the use of improvised means if you value the product. For example, professional tools should not be sharpened this way - you can ruin them forever.

How to sharpen scissors at home using improvised means

Peculiarities. This method is suitable if the product has only slightly lost its sharpness. This method will not save a very blunt instrument.

1. Fold a sheet of fine-grit sandpaper so that the abrasive side is on top.
2. Cut the paper into long strips so that the entire length of the blade is used.
3. Make about 20 cutting movements.
4. Wipe the blade to remove any sandpaper chips.
5. Check the sharpness - the result will surprise you.

Sandpaper will help if you need to sharpen zigzag scissors with your own hands. This tool is distinguished by a characteristic blade edge, so sharpening it with a bar is difficult.

Peculiarities. If you need maximum sharpness, cut many thin strips. When you just need to sharpen a tool, it will be enough to make a couple or three wide strips.

1. You will need a 25cm sheet of foil. Fold it lengthwise several times to create a fairly thick strip.
2. Cut the material into strips.
3. Make sure that the entire blade is used (base - tips).

If you urgently need sharp scissors, use one trick: the more layers you make by folding the foil sheet, the stronger the sharpening effect will be in one cut.

Peculiarities. During sharpening, residues fly off from the sponge. There are many of them and they are small - it will be difficult to remove. Sharpen directly over the trash can so you don't have to clean up later.

1. Take a metal kitchen sponge. If you have a choice, it is better to take the one that is softer.
2. Cut the sponge using the entire blade.
3. The more cuts there are, the sharper the tool will become.

Peculiarities. This makes it convenient to sharpen small scissors, for example, for cuticles. At the same time, sharpen your nail clippers if necessary.

1. “Cut” the needle. When closing the blades, try to guide the needle along the cutting edges.
2. Apply a minimum of force: cutting movements should be light.
3. Continue cutting until the blade becomes sharp.

Instead of a needle, you can take a sewing pin, knitting needle or screwdriver. The main thing is that the essence of the method is not lost - you need to cut using metal.

Peculiarities. You need to use a jar that is not needed: it will later have scratches. If you need to sharpen a small item, it is better to use a bottle with a narrow neck.

1. “Cut” the jar: the blade should slide and the container should slide back.
2. The cutting movements must be repeated until you are satisfied with the result.
3. Wipe the blades; there may be glass dust on them that is not visible.

Remember that traditional sharpening methods are designed for immediate results. To keep the scissors “in shape”, you will have to return to the chosen method often. Or still take the products to the master.

If the problem is not in the blades

Scissors do not always cut well because of dull blades. Before sharpening a tool, check whether it is really necessary. Inspect the fastening of the blades: when it becomes loose, the scissors stop performing their function and simply “chew” the material. In this case, it is easy to return them to “functionality” - just tighten the threads.

https://www.youtube.com/watch?v=6tZy4hnx8AE

The easiest way to solve the problem of a loose fastener is if the blades are connected with a bolt. The product must be opened and the fastening tightened using a screwdriver or other scissors. If the manufacturer used a rivet as a fastening element, then you will have to “tinker” longer than in the case of a bolt. To tighten the fastening, you need to flatten the plug with a hammer. The scissors are placed on a flat, durable surface in an open form and get to work.

Always tighten the product when it is open. Otherwise, it may simply not open after manipulation. If after tightening there is still a gap between the ends, try filing the stopper. It is under the rings.

Sometimes it is enough to apply a spindle (a lubricant intended for sewing machines) to the axis, and the “operability” of the tool returns. Don't pour too much - one drop is enough.

Although sharpening scissors at home without special tools is possible, it is easier to prevent them from becoming dull than to deal with it later on your own.

To maintain the sharpness as long as possible, you need to use scissors for their intended purpose:

• If the tool is intended for manicure, it is strictly forbidden to cut cardboard or fabric with it.
• Those who are interested in sewing should acquire several models for a specific task.
• When sewing clothes, you often have to cut metal threads and zippers, and if you do this with cutting scissors, they will quickly become dull.

This is one of the most common tools, which is available in every family for cutting all kinds of materials, but does not always perform its tasks clearly enough.

Rough operation is caused by improper sharpening of the blades or unbalanced movement of the cutting edges.

Eliminating them is quite simple for anyone with a regular set of sharpening devices. To do this, it is necessary to understand the principles of creating a cut.

The article provides advice to the home craftsman on how to sharpen scissors and adjust their blades for proper DIY work at home, with explanations along the way using pictures, diagrams and a video.

To understand the principles of sharpening and setting up a tool, you should understand its design and the basics of cutting the materials being processed.

How scissors are designed and work

The well-known children's riddle about two ends, rings and nails fully reflects the design and operating principle of this instrument.

Scissors consist of two symmetrical halves connected by a common axis of rotation. The cutting force is created due to the occurrence of a torque, the magnitude of which is influenced by the length of the lever.

Knife blades have working surfaces ending in a cutting edge. The ends can be of different shapes:

1. sharp;
2. rounded;
3. combined.

The axis of rotation is usually performed by a screw mechanism with the possibility of slight adjustment of the preload.

Blade geometry

Hairdressing scissors have the best surface shapes. They are designed for the delicate work of cutting hair, made of durable steel with well-sharpened counter-moving cutting edges.

The cutting edge of each half slides with one side along the common cutting plane towards the material being processed. The cut is created due to the sharpness of the blades and their minimal approach to each other.

The sharpening of the blade, unlike a regular knife, is created by a one-sided approach.

Cutting force

It should be taken into account that each tool is manufactured to work under certain conditions. For example, hairdressing scissors are made straight. The loads they experience are minimal. It is not advisable to use them for other purposes: they are easy to damage.

Garden shears can cut tree branches, and the surface of their blade is formed with three zones of developed loads:

• the recess closest to the axis of rotation allows you to generate maximum cutting force;
• the next one is the average;
• the remaining part is intended for cutting thin branches.

In this case, the effect of creating a bending moment through the lever is used: bringing the material being processed closer to the axis of rotation increases the shear force, and moving it away decreases it.

Typical defects

Any scissors can work poorly for two reasons:

1. the blades came apart;
2. the cutting edge of the supply has become dull.

How does a gap occur?

If the scissors are made of soft alloy steel, then when large loads are placed on the blade, the latter may become deformed and move away from the cutting plane. In this case, they will further bend the material rather than cut it.

Such a defect is easy to detect if you look at the gap between the shifted blades.

How to adjust blade stroke

The reason for the divergence of the surface of the edges may be:

1. loosening the screw clamp of the rotation axis;
2. metal deformation due to the application of increased loads;
3. a combined manifestation of both faults.

In the first case, just tighten the screw: the scissors will cut normally. If there is a bend in the plane of a thinner blade (they are most often created of different thicknesses), then it should be given its original shape.

It is unlikely that it will be possible to bring hairdressing scissors to an ideal level in this way. However, household models designed for cutting paper or fabric can be adjusted by making a convex bend on the surface so that when processing the material, both blades touch, being in a common cutting plane.

Cutting edge irregularities

The metal of the scissor blade, like a knife, wears out over time.

It is periodically required to be sharpened and the surface of the cutting wedge to be formed. Depending on the purpose of the tool, the edge is formed:

• regular sharpening;
• or additional polishing of its surface.

Hairdressing scissors do not polish their edges when sharpening. Thin grooves from fine-grained abrasive materials located on the inlets hold hair well when cutting.

Sharpening methods

A professional approach angle is formed on special machines in the factory. It must be preserved and maintained. The article does not discuss factory technology, but publishes simplified methods available to the home craftsman for bringing household models into working condition.

Sharpener

The blades of the scissors are spread apart and alternately pulled through the slot prepared in the tool. The supply metal is ground down with abrasive materials. Rotating disks can be used for this. All nicks and irregularities are removed to a single level.

Various types of sharpeners can be purchased through Chinese online stores.

Diamond needle file or file

When sharpening, scissors should be firmly fixed or held tightly in your hand, resting it on some stationary object, for example, a table surface.

The cutting surface of the file must be positioned in only one plane. This technique ensures the same sharpening angle along the entire length of the blade. Its factory value must not be violated.

If there is a large notch on the surface of the file, additional polishing of the lead with another tool may be required.

whetstone, whetstone, whetstone

It is advisable to disassemble the scissors, but you can also work in assembled form. The technology is the same as when sharpening a knife using these devices. The supply is placed on the surface of the sharpening stone, the blade is directed in one direction, and the same angle of inclination is maintained at all times. The abrasive material is periodically moistened with water, removing particles of cut metal.

The photo shows work on a homemade whetstone made from ceramic tiles with your own hands.

If the shape of the blade differs from a straight line, having a convexity or concavity, then the direction of sharpening movement is changed by 90 degrees.

Sandpaper

Select varieties with the smallest grains - zero. Cut it along the entire length of the blade. The abrasive material of the sandpaper, passing under the cutting edges, sharpens them.

Food or technical thin foil

The material is folded in several layers, cuts are made along the entire length of the blade.

Foil kitchen sponge

This method works according to the technology of the previous one. Scissors should work along the entire length of the blade.

Glass bottle

Grasping the neck with both blades, make cutting movements along their entire length in both directions. Surfaces are polished. Therefore, the plane of the inlets is positioned in the optimal direction for their alignment.

Needle, screwdriver or steel wire

By squeezing and unclenching the scissors, they are simultaneously processed with force along the entire length of the blades with the inserted needle.

Manicure scissors

A characteristic feature of this tool is its curved, curved blades. It is better not to start processing them without good metalworking skills and round fine-grained diamond-coated needle files.

If your nail scissors start to work poorly, try this first:

• tighten the screw fastening of the rotation axis;
• inspect the gap between the cutting edges of the leads;
• polish with a needle.

I recommend straightening bends only as a last resort, using a specialized tool.

To consolidate the material, I recommend watching Serg578’s video “Tweaking the blade of scissors in 2 touches.”

Sharpening tailor's scissors

With the help of good professional tools, you can make any single job much easier and more enjoyable. Tailor's scissors were no exception, because it is very important to cut fabric well in tailor's work. One wrong move with scissors and the fabric will be damaged, and this should not be allowed especially when cutting expensive fabrics. For high quality work, periodic sharpening of tailor's scissors is required.

A variety of scissors are very popular and in demand - with a short or long blade, with edges of different shapes, they can be straight or sharp. All of them cut the material well, without crushing or chewing.

A good tailor should have several different scissors in his kit, each of them is designed for different types of work: for cutting fabric, for cutting patterns, zigzag scissors and even manicure scissors, they are used to make notches and undercuts.

Thin-bladed scissors allow for greater cutting precision, while zigzag scissors allow you to cut fabric without further finishing of the edges.

The cost of sharpening tailor's scissors is from 250 rubles

A good craftsman is obliged to monitor the condition of his working tool, so you need to sharpen your tailor's scissors; they will serve you for a long time and help you carry out your orders efficiently. You need to take good care of your scissors. Under no circumstances should tailor's scissors be used for anything other than their intended purpose. This makes them dull very quickly.

You can hardly get pleasure from working with dull scissors, and the fabric will be damaged if the scissors chew the fabric. In order to keep them in perfect order, it is necessary to sharpen the scissors on time. For this purpose, there are special workshops where professionals will quickly and efficiently tidy up dull blades.

After sharpening the scissors, the blade blade should be perfectly smooth along the entire inner side of the blade. The slightest burrs, especially at the beginning of the web, can lead to the material biting.

Some tips important when buying tailor's scissors

When choosing good scissors, make sure that there is no space between the blades; the best metal is considered to be stainless steel that has undergone a hardening procedure. This metal lasts much longer, it is easy to sharpen and sharpening lasts much longer.

A prerequisite for good tailor's scissors is the screw that holds the two halves of the blades together. This is important so that at the right time you can tighten the scissors if they become loose. The handle should be comfortable and the rings should fit the size of your hands. Not very small and not large, in this case they will be easy and convenient to use.

How to keep your scissors sharp as much as possible

From time to time, tailor's scissors need to be sharpened, just like any other cutting tools. The effect of good sharpening can be preserved for a longer period. Therefore, taking care of such an important tool is very important. They need to be cleaned after use, lubricated as necessary and kept in a dry place, preventing the ingress of moisture and various liquids.

The cutting part of the scissors should be kept clean to avoid ragged cuts. To prevent scissors from rusting, they must be periodically lubricated with high-quality sewing machine oil.

If you follow all of the above, the scissors will have to be sharpened much less often, and you won’t have to change them often. A careful attitude will save a lot of money in your budget. Scissors that have lost the ability to cut well can be easily corrected by taking them to a sharpening workshop. There, your scissors will be quickly and efficiently sharpened using special equipment and they will again delight you with their impeccable work. The work will bring you pleasure, and the completed order will bring you income.
