How to sharpen scissors with a needle

How to sharpen scissors at home

Scissors, especially if they are professional, need to be sharpened using a special machine. It's better if a master does it. But it’s not always convenient to turn to specialists, which forces you to sharpen scissors at home yourself. You can find a lot of advice on the Internet, which is sometimes too strange. For example, use sewing needles or a glass cup.

• Scissor cutting edge
• High-quality sharpening work
• Professional scissors

Scissor cutting edge

All scissors cut fabric precisely with the edges of the blades, which must be sharpened. The angle of the cutting edges is made at different angles, this is influenced by the purpose of the scissors. For example, scissors, where the angle of the edges is 90 degrees, are intended for office work. But, if such a tool is well sharpened, it will cut fabric and other soft materials.

Note! Tailors' scissors are checked for good sharpness using fine fabrics. For example, you can take silk or chiffon. You need to make sure that the tips of the tool also cut the fabric. This indicates an ideal job done. This tool can cut any fabric.

There are scissors that look sharp, but in fact cannot cut fabric. This is influenced by many factors. For example, loose blade fastening. Over time, the scissors become loose and require additional correction. To determine which mount, pay attention to the gap between the edges. If there is one (even a small one), you need to tighten the screw. Then carry out testing again.

High-quality sharpening work

If tightening the screw does not help and the scissors still refuse to work, you need to sharpen them. High-quality sharpening is obtained using an electric sharpening apparatus. It is not necessary to go to a workshop; you can buy such a device and master it at home. It is better to start work not with scissors, so as not to spoil them.

The sharpening machine can sharpen absolutely any tools, regardless of their wear. Before sharpening the scissors, the screw is unscrewed so that the blades do not interfere with each other in their work. In this form, it is easier to clean the tool from debris and sharpen the tips of the scissors efficiently. Before work, be sure to wear gloves, preferably leather ones. This will protect your hands from damage.

High-quality and reliable scissors are expensive, but they can last for many years. List of the most popular ways to sharpen scissors:

• File;
• Sewing needle;
• Diamond wheel;
• Sanding paper;
• Sharpening special apparatus;
• Household tools;

When sharpening a tool using the above methods, it is not always possible to do it well the first time. Therefore, the procedure must be performed two or three times.

Professional scissors

Nail scissors are one of these small tools. The angle of the cutting edges is very different from all the others. Sharpening requires careful, painstaking work. If the scissors have straight blades, then they can be sharpened using a sharpening machine with a diamond wheel; you must have the appropriate skill. The speed of the circle should be minimal. The blades of the scissors are drawn from their tip to the axis; physical force must not be applied.

How to sharpen scissors at home - Metals, equipment, instructions

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.

How to sharpen scissors at home with a needle

Scissors are an indispensable attribute in any family. Over time, their blades lose their sharpness. Fortunately, almost any scissors can be sharpened.

How to prepare scissors for sharpening

Before you start sharpening, check whether the performance of the blades is actually affected by dullness. Sometimes scissors may not cut well due to the loosening of the connecting element. It could be a bolt or rivet.

After fixing all the problems, cut something and thereby check whether sharpening is needed. If the blades do not cut well, you will need to sharpen them. Before use, wipe the knives with a cotton swab and an alcohol solution. Remove more stubborn stains using suitable chemicals.

Self-sharpening methods at home

There are many ways to sharpen scissor blades at home. To do this, you can use improvised materials that are found in almost every apartment.

Needle or awl

To sharpen you will need a thick needle or awl. The method is quite energy-intensive, so it is suitable for processing small scissors.

Cut the selected item from the rings to the tips of the blades. Try to guide the needle along the sharp edges. Your actions should not be performed through force.

Metal sponge

You can use either new or used metal sponge. The softer the sponge, the better.

Cut the sponge with scissors, using the entire surface of the blades. The more cuts you make, the sharper the blades will be. Please note that during the procedure the sponge crumbles a lot, so it is better to cut directly above the trash can.

Glass jar or bottle

In this procedure, it is best to use an unnecessary jar, since after sharpening there will be scratches on the glass.

• Take the jar in your hand and make the required number of cutting movements. During sharpening, the entire surface of the blades should touch the glass.
• After work, carefully remove small glass fragments from the surface of the blades.
• If you need to sharpen small scissors, use a glass bottle with a narrow neck.

Foil

Take a sheet of foil and fold it into 6-8 layers. You should get a fairly dense layer. Cut the foil into small strips, using the entire surface of the blades. The duller the knives, the more cuts you need to make.

Special sharpeners

A special sharpener can be purchased at a hardware or construction department or ordered from an online store.

Open the scissors and slide each blade through the designated hole. Do the required number of passes until the blades become sharp.

Sandpaper

Like other available materials, scissors are sharpened with sandpaper by cutting it. First, fold the paper in half with the rough side facing out and cut into small strips.

The finer the sandpaper grains, the better. The ideal option would be zero-grit sandpaper.

File

Open the scissors to their maximum width and hold with your hand where the blades meet. This will allow each half to hold tightly and not become loose during the procedure.

File the inside of each blade at a 70 to 80 degree angle. Make movements either only from yourself, or only towards yourself. Never saw the blades by jerking back and forth. Just a few movements are enough to sharpen.

If you cannot hold the scissors tightly with your hand, use a vice.

Grindstone

A similar stone can be purchased at a hardware store or hardware store. Before sharpening, separate the scissors into their component parts by unscrewing the central screw. Apply each blade in turn to the stone with its sharp side and make several movements towards or away from you until the desired sharpness is achieved. At the end of the procedure, assemble the halves by connecting them with a central screw.

Grinder

To use a sharpening machine, sufficient experience and dexterity is required.

The machine is a device with a rotating abrasive wheel. Simply turn on the device and place the halves on the sharpening disc.

In the procedure, it is extremely important to know what angle must be maintained between the blade and the wheel, as well as how long to sharpen, so if you are not familiar with the device, give preference to another method.

Paper clip

Please note that the larger the paperclip, the better.

Hold the paper clip tightly with the tips of the blades and slowly, squeezing the scissors with your fingers, draw it to the base. Repeat the procedure until the scissors are sharp enough. You'll know the scissors are sharpening when you notice small nicks in the paper clip.

Battery

In a similar way to a paper clip, you can sharpen scissors using an unnecessary AA battery. Please note that the battery must be in a metal casing. Clamp the battery with the blades and move it to the base the required number of times.

Screwdriver

Since the paperclip or battery is quite small, it can be replaced with a screwdriver to sharpen larger scissors. Place the screwdriver, metal side down, on a hard surface. Pinch it with the tips of the blades and slowly move it to the base. Repeat as many times as needed to keep the blades sharp.

Where can you sharpen scissors?

Typically, this service is provided in key-making or shoe repair shops. The cost of sharpening scissors is from 50 rubles, depending on the complexity of the service.

Subtleties of the sharpening process

Depending on the type and purpose of the scissors, sharpening may have some subtleties and nuances.

Regular

Scissors that cut paper or other materials can be sharpened at home, spending very little time. Use foil, sandpaper, or another metal-coated object to sand the blades.

Kitchen

At home, it is best to sharpen kitchen scissors in a way that does not require disassembling them. Foil, sandpaper or metal sponge work well. However, such sharpening will not provide long-term results. For better processing, contact professionals.

Manicure

High-quality manicure scissors are quite difficult to sharpen at home. To do this, you need to know how to properly tighten the connecting element and what the sharpening angle should be. The blades are processed with a special diamond needle file from base to tip.

How to sharpen scissors at home video

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:

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.

How to sharpen scissors at home video

Very often the question: “How to sharpen dull scissors at home?” - the answer follows that with a sharpening price of 200-300 rubles, it’s easier to throw them away and buy new ones. However, such advice is most likely only suitable for cheap stamped products made from ordinary structural steel, although it is still better not to throw them away immediately, but to try to sharpen them using available means.

Good household, tailor's and hairdressing scissors are made of durable carbon steel and they are not cheap. Proper sharpening of such a tool is only possible with the use of an abrasive, and you can do it yourself at home. Several simple and affordable methods using scrap materials allow you to slightly correct the cutting edge.

The following describes the best home methods for straightening and sharpening scissors, with which you can restore the cutting properties of this household tool in a short time.

The main mistakes when sharpening scissors

The main conditions for proper operation of household scissors are a tight fit of the knife parts, the correct slope and sharpness of the cutting edge. According to GOST R 51268-99, the sharpening angle of hairdressing scissors should be 60° with a deviation in accuracy from +5 to -15°, and for household, tailoring, etc. scissors - 70° with a possible deviation of ±10°. The surface finish of the internal part and the chamfer of the blade must correspond to the pre-grinding roughness class.

Sharpening scissors at home does not require strict compliance with all these requirements, although this should be strived for. The main mistakes made during home sharpening are:

• linear and angular unevenness of the cutting edge;
• non-compliance with the standard sharpening angle;
• Using too coarse abrasive.

As a rule, the cause of the first two errors is unreliable fixation of the blade in a given position or incorrect operation of the sharpening tool. If the first is quite difficult to achieve at home, then with the second everything is simple: working movements of the blade along the abrasive should be performed only in one direction.

Sharpening methods depending on the type of scissors

There are various types of scissors used in the household, which have different blade shapes and differ in size.
Yes, this includes not only household, stationery, hairdressing and tailor's scissors, but also such home varieties as gardening and manicure scissors.

Some of them have specific cutting edge angles, many are non-separable, some household scissors are made of hard carbon steel, while others are made of ordinary structural steel.

In order to sharpen them correctly at home, you must follow the following rules:

• rigid fixation of the blade being sharpened to ensure uniform geometry along its entire length;
• exact following of the inclination of the sharpening tool to the angle of the cutting edge;
• performing home sharpening from the handle to the end of the blade;
• movement of the sharpening tool in only one direction (most often away from you).

The following are brief descriptions of the sharpening features of the smallest and largest representative of the household scissors family.

Features of sharpening manicure scissors

Homemade manicure scissors have an arched shape, so even a slight inaccuracy in their fastening causes a large divergence at the ends of the blades. Therefore, before you start sharpening them at home, you first need to eliminate the mounting play. If it is a screw, then the adjustment is made with a screwdriver, and if it is a rivet, then it can be carefully unfastened using a punch or a similar tool, which can always be found in the arsenal of a home craftsman.

To sharpen the cutting edges of this home manicure tool, you will need a thin diamond-coated needle file.

Since their width is only two to three millimeters, some home craftsmen use a magnifying glass with a mount during their work. To fix the scissors, you can use a small homemade vise or a device made from a clamp and wooden blocks.

How to sharpen garden shears

To properly sharpen garden shears in a home workshop, you need a vice, a flat file and a sheet of sanding paper. The scissors can be sharpened in assembled form, but it is better to disassemble them into two halves by unscrewing the nut and removing the tightening screw.

Extraction of the cutting edge should begin from the handle, gradually moving towards the end of the blade. The file must be held strictly along its inclination, and they must be moved only in one direction (usually this is done away from oneself).

It is necessary to remove burrs from the treated half, for which its inner plane is ground in a circular motion on a sheet of abrasive paper.

How to sharpen homemade scissors

In order to sharpen dull scissors at home, you can use both a traditional abrasive tool and proven folk methods, although some of them seem unusual. It should be understood that when using grinding bars and wheels for home sharpening, the entire cutting surface is processed, and in other cases, only a slight correction of its pointed edge is performed.

Using a sharpening machine

It is very convenient to sharpen home cutting tools on a special sharpening machine, which is equipped with a device for clamping the product at a given angle and its fixed movement along the grinding wheel. However, this type of equipment, as a rule, is available only in special workshops or among craftsmen who make knives at home.

In principle, in order to sharpen cutting edges to the required sharpness, an ordinary electric sharpener, which is in the arsenal of almost every home workshop, is also suitable. For high-quality home sharpening, a support table is required, since the blades will have to be fixed manually, both in angle and length.

If you have no experience working on such a home machine, then before sharpening the scissors it is better to practice on an unnecessary piece of metal, since it is very easy to ruin them due to inexperience on a home electric sharpener.

Use of whetstone

In the household, the most popular sharpening tool is the whetstone. Usually this is a flat rectangular block of fine abrasive, which can be purchased at any tool store. This type of home sharpening requires steady hand and some skill, but if all recommendations are followed, it gives one of the best results.

Before starting work, place the block on a piece of cloth and moisten its surface with water. If the household scissors are non-separable, then it must be placed on the edge of the table. If they can be separated, disassemble the scissors into two halves by unscrewing the fastening screw.

Then, holding one of the parts by the ring and handle, fix it at the angle of inclination of the cutting edge and move it with pressure along the surface of the block several dozen times. The movement should be performed away from you and only in one direction. As you work, regularly inspect the blade and, as soon as it looks smooth and sharp, move on to the other half.

After finishing home sharpening on a block, wipe both halves with a napkin and then connect them with a screw.

Using a vice and file

Flat files are used to sharpen the edges of medium and large-sized household scissors.
and this prerequisite is their fixation in a bench vice. For sharpening, ordinary files No. 3–4 or with diamond coating are most often used.

Any vice is suitable for this type of work - like those found in any garage or home workshop. When clamping household scissors, they should be carefully aligned vertically, and it is desirable that the end of the blade is completely clamped by the jaws of the vice. They work with a file on their own, moving it strictly in accordance with the angle of the cutting edge.

After processing, it is necessary to remove burrs from home scissors using sanding paper.

Sharpening with aluminum foil

This is one of the simplest and most affordable ways to sharpen scissors, because in this case, foil is used, which is used by housewives for baking. To sharpen them in this way, you need to take a piece of foil 20–30 cm long and fold it several times.

Then you need to start cutting thin strips along the entire length, periodically checking the sharpness of the blade on a sheet of paper.

This method, like all others, is called home sharpening, although in fact in this case only light editing of the cutting edge occurs, which gives only a temporary result.

We use sandpaper, sponge and steel wool

Probably the most popular home method for quickly sharpening homemade scissors is cutting with sandpaper. As in the case of aluminum foil, here only the cutting edge is straightened, but with obviously good results. For these purposes, sandpaper with the GOST designation of 10-N and 20-N is best suited.

Before starting work, the sandpaper should be folded in half with the abrasive part facing out. You need to cut it into small “noodles” so that the cut covers the entire length of the blades. After a couple of dozen cuts, it is necessary to check for sharpness using a sheet of paper. In addition to sandpaper, metal wool and Scotch Brite, an abrasive sponge that many housewives use to scrub burnt dishes, are well suited for these purposes.

Metal needle

Dressing the cutting edge with a metal needle also affects only the very edge of the tip of the blade edges. This method uses a thick needle, which is found in every household. First, you need to grab the can in the middle with the part of the blades closest to the handle. Then, squeezing the rings, make it slide along the cutting edge to the very end, repeating this procedure until the desired result is achieved.

This method is not particularly popular among housewives, because it requires special skill and seems dangerous.

Application of glass jar

Using a glass jar as a tool to restore the sharpness of the edges of homemade scissors causes a skeptical grin from many, but there is evidence that the result in this case is no worse than when cutting with sandpaper.

This home sharpening looks like this: a glass vessel with a diameter of 10–12 cm is held on the table surface with the left hand, and with the right hand, using homemade scissors, an attempt is made to cut it in half. First, the glass is grabbed by the base of the scissors, wide open to the full width, and then their blades slide along the glass surface to the very end.

In this home method, small particles of glass act as an abrasive, which break off when the metal moves over its surface.

How to keep scissors sharp

The first rule for keeping scissors sharp is to always use each type of this household tool only for its intended purpose. This is especially true for hairdressing and tailoring tools. It is also necessary to remember that household scissors are ordinary metal products made of carbon steel with a thin chrome coating, which are subject to oxidation and rust when sharpened or scratched.

After any contact with water, household scissors must be wiped dry, and they must be stored in a place inaccessible to moisture.

The article lists the most popular home methods for sharpening scissors. But some sources write that cutting foil and sandpaper creates an uneven cutting edge, and after that it is more difficult to sharpen. What do you think about this? Please share your thoughts in the comments to this article.

How to sharpen scissors at home

In the household, scissors are one of the indispensable household items. Each of us can find at least 2 types of such tools at home: manicure and stationery. In addition to the main types, people use other types: garden, for cutting hair, for cutting, etc. Their service life depends on the quality of the steel, but even very good blades need sharpening. You can cope with this task at home, without resorting to the services of a sharpener.

How to sharpen scissors yourself

With constant home use, the need to sharpen the tool occurs no more than once every 6 months. With constant sharpening, the blades gradually wear down, so sooner or later you will have to buy new ones.

Cheap Chinese scissors, which are sold in abundance in our markets, become dull very quickly; in addition, due to low-quality parts, the fastening of the metal halves itself is very fragile and breaks quickly.

More durable, high-quality products are expensive, but they also last for decades. The most popular sharpening methods are:

• Using a needle.
• Sandpaper.
• With a file.
• Diamond wheel.
• Using a special device.

You can sharpen the blades of household scissors using a regular set of household tools. Sometimes you have to repeat sharpening several times to achieve the effect.

Before you start sharpening, the tool needs to be prepared.

1. Remove all remaining dirt. To do this, take a cotton pad soaked in alcohol and thoroughly wipe the working part of the product.
2. It is necessary to check the tool for defects. It often happens that when folding the halves, a gap is formed, the ends are damaged or do not meet, and the mechanism itself does not move well during operation.

If the fastenings between the sheets are loose, they need to be tightened; for this you will need a screwdriver, pliers or a hammer. It all depends on the type of fastening, it can be a screw or a rivet. The screw can be tightened with a screwdriver or pliers.

Important! The screw must be tightened very carefully, otherwise the mechanism will jam and the scissors will no longer be repairable. It is possible to turn the screw no more than 0.5 mm.

In the case of a rivet, you need to use a small hammer or anvil. The scissors should be opened and secured on a flat surface, using a hammer to flatten the rivet plug. There should be a limiter on the inside of one of the tool rings. If the blades do not meet tightly when closed, then you need to file the stop a little.

Other defects such as creases, nicks, formed rust stains, etc. can only be eliminated by a master.

A quick way to sharpen with a needle

How to sharpen scissors if there are no specialized tools at hand? The solution may be an ordinary gypsy needle. If you don't have one, you can use a narrow glass bottle.

Method of sharpening with a needle:

1. The scissors need to be opened as wide as possible.
2. Place the needle at the section.
3. Gradually close the scissors, thereby moving the needle down towards the blades.
4. The procedure should be repeated 2-3 times.

If a bottle is used instead of a needle, then between the sections you should squeeze the neck and close the tool in the same way as when cutting the material.

Using Sandpaper

Another quick way to quickly sharpen your tool. To work, you will need sandpaper (any abrasive).

1. The sandpaper sheet needs to be bent in half (so that the abrasive is on the outside).
2. Use scissors to make several cuts on the paper.

The sandpaper slightly sharpens the dull tips of the cutting blade, but after a little time the blades will become dull again. Such paper cannot grind off the required thickness of steel, so this option is only suitable if something needs to be cut urgently.

How to sharpen hair scissors with a file

As for hairdressing scissors, everything is much more complicated. The fact is that sufficiently sharp blades will cut dense and loose materials differently. Our hair is very thin, so hairdressing tools need to be sharpened in a special way. The file copes well with the task of sharpening, but to implement this method you need to make physical efforts.

Sequencing:

• Prepare and clean the scissors (with cotton wool and alcohol).
• Open them as much as possible, the tips of the blades should look up, the rings should be fixed by hand so that the sharpening angle does not change.
• You only need to sharpen the inside of the tool (at an angle of 60-70 degrees).
• You need to run the file several times, towards yourself, from the beginning of the blades to the joint.
• Blades can only be sharpened in one direction.

After such sharpening, you need to check the quality of work on any thin oilcloth (polyethylene). If the tool cuts well and does not jam the surface, then sharpening was a success.

How to use a special device

You can purchase a special sharpener for knives and scissors at any hardware store. Such devices are suitable for tools with sharp ends. Special manicure products for cuticles have rounded ends; a sharpener cannot handle this shape.

The sharpener has special convenient holes for the blades. The scabbard must be sharpened in the direction from the tip of the tip to the axis. For a good result, you need to walk through a special nozzle 5-7 times.

Sharpening nail scissors with a diamond wheel

Using a diamond wheel, you can process tools no worse than using professional tools.

Important! You can sharpen small parts with professional tools and diamond bits only if you have the appropriate experience.

A diamond wheel is best for smaller, more fragile metal parts, such as a manicure set. You need to work with the device extremely carefully, do not change the sharpening angle, otherwise the scissors will become unusable. The rotation speed of the circle should be minimal. You need to sharpen smoothly, from the beginning of the tip, without strong pressure. If after the first sharpening there is no desired effect, then the panels need to be sharpened to the required sharpness.

Instead of a diamond wheel, you can use a diamond nefil. The scabbard must be ground down gradually using the same movements from the tip to the rings. For manicure or hairdressing tools, you need to have 2 types of diamond nefil (coarse-grained and fine-grained). First, the sheath is treated with a large abrasive, and then with a fine one. Thanks to this method, both cutting parts will be ground equally.

What is forbidden to do with scissors: useful tips

Gardening or office tools may not be used for years, while every person needs manicure tools at least once a week. In order to extend the life of your favorite tool, you need to use the following tips.

• Tip No. 1. Despite numerous tips, you should not boil scissors for disinfection, as the tools will rust very quickly. Today, you can buy inexpensive antiseptics at the pharmacy that can be used to treat metal after use.
• Tip No. 2. Once every 6 months, the layout mechanism needs to be oiled. To do this, you need to drop a couple of drops of any oil (vegetable, olive, castor, etc.) into the area where the axis opens. Oil lubricates the backlash and prevents corrosion.
• Tip No. 3. The mechanism cannot be disassembled; some parts cannot be reassembled.
• Tip No. 4. Use the tool only for its intended purpose: manicure tools - for manicures, garden tools - for trimming branches, hairdressers - for hair. Improper use will cause the blades to quickly become dull.
• Tip No. 5. You cannot grind metal along the entire thickness of the scissors; a special sharpening angle is needed specifically for cutting the material. If you grind off the entire area of ​​the canvas, the scissors will stop cutting. They will also stop cutting if you choose the wrong angle when stitching.

It should be understood that it is better to give a professional tool to a master. For example, thinning scissors cannot be sharpened to the required sharpness at home.

Buying new scissors instead of old ones is the last thing you can do if your tool cannot be sharpened. You can always try to revive the instrument by contacting a specialist. The master will align the blades and be able to sharpen the scissors even better than at the factory.

will talk about home sharpening of tools.

How to sharpen scissors in a couple of minutes: 3 simple ways + a method for experienced craftsmen

In many families, the same scissors are used for all purposes at once: the housewife can cut fabric with them, the father trims some wiring once a year, and the children will definitely try to cut a television antenna into two parts.

It is clear that not everyone, even the most hardened metal, can withstand such tests of fate, so it would be good to periodically sharpen the scissors. Plus, it's quite easy to do. In this article we will look at 3 traditional methods + the sharpening method using a tool.

Traditional methods

These tips are passed down from grandmothers to granddaughters and have already become legendary. However, they are quite simple. By the way, I would like to separately note one of the common reasons for the poor performance of scissors: a loose screw or rivet (depending on the device). Adjustment and sharpening of scissors according to any principle must begin with tightening this fastener.

If adjustments cannot be made with a screwdriver or wrench, place the scissors on a metal surface and lightly tap the fastener with a hammer. But not too much: the scissors should not be too tight.

So, with that out of the way, let's move on to the methods of sharpening scissors.

With a needle

it is necessary to place the needle between the cutting edges and imitate cutting movements, as if rolling the needle back and forth. As a rule, a couple of minutes are enough to feel improvements.

using foil

fold the foil in several layers and simply cut it into small strips. repeat the procedure several times and the scissors will quickly become sharper

using sandpaper

The principle here is the same as with foil, but due to the fact that the layer of sandpaper is usually on one side, it is necessary to turn the scissors over from time to time so that sharpening occurs evenly.

sharpening scissors using a needle file

If you are a skeptic in life and are already thinking about what to write about the author in the comments, you may like the following method

In fact, there is nothing difficult about sharpening with a needle file. It is necessary to clamp the scissors in a vice and select the correct sharpening angle. The correct sharpening angle will be the factory one. You will find this edge on any scissors. Just attach the file to the existing sharpening and start moving according to the “forward + sideways” principle

It is necessary to sharpen the entire length of the blade. A needle file with a fine, frequent notch should be used. If your tool has a cut type according to GOST, choose number 3.

Don't get carried away: as a rule, a couple of minutes of work is enough.

How to sharpen scissors: sharpening at home with a needle, file and whetstone - Cleaning Pro

Many people prefer to throw away scissors that have become dull. But it’s better to learn how to sharpen scissors, and thereby save significantly on their purchase.

After all, now on store shelves you can only buy modern, unreliable Chinese fakes.

Preparation

The easiest ones to sharpen are stationery scissors and haircut scissors. It is much more difficult to sharpen a manicure set. Before sharpening them, you need to make sure that the malfunction is due to dullness.

It is quite possible that their fastening axis is simply weakened, where a bolt or a simple rivet is mainly used. Just tighten the bolt.

If the screw is tightened tightly, but the scissors still do not cut well, then sharpen the stop heel, which is located near the hole with the bolt.

Do not try to close the blades, as this will make the situation worse.

If a rivet is used at the joint, tighten it. But before that, open the scissors and place them on any metal object.

Then, using a bit, flatten the rivet and check how well the blades close.

If nothing has changed after these steps, you will need to sharpen the scissors at home.

Procedure

To sharpen scissors, you need to use a whetstone. It can be purchased at many hardware stores.

Most stone varieties have two different sides, one being fine-grained and the other being coarse. You need to use the rough side first.

How to sharpen scissors yourself? The algorithm includes several steps.

1. Place the whetstone on a cloth and dampen it a little with water.
2. If a bolt is used as a fastening on the scissors, then disassemble them. If using a rivet, open the blades as wide as possible.
3. Make sure that the factory sharpening angle is maintained. Don't change it. It is required to lay the blade in such a way that its plane tilts away from itself.
4. Make sure that the chamfer is parallel to the surface of the block.
5. Sharpen the scissors correctly, slowly move the blades along their entire length and only in one direction.
6. Once you have sharpened them on the rough side of the stone, start sharpening them on the other side. Do the same steps.

Once you've finished sharpening, test the scissors on a piece of fabric. If they are well sharpened, they will cut the material evenly while hanging without any problems.

Sharpening nail scissors: how to do it right

To sharpen nail scissors correctly, you need to use a small whetstone with a fine grain.

Give preference to sharpening stones with diamond chips.

Nail scissors can be sharpened in the same way as regular ones. But this should be done as carefully as possible.

This is especially true for sharpening the inclination of the cutting chamfer, since it differs from others.

If your nail scissors with curved blades become dull, it is easier to buy new ones.

The only thing that can be corrected in them is the bolt.

Quick Methods

In order not to waste time disassembling and turning the presented tool, you can use the following methods.

1. Sandpaper. Find a small piece of this material, fold it in half, with the rubbing side facing up. Start cutting the paper into about 15 strips. In the same way, you can use an abrasive material on fabric, metal wool.
2. Aluminium foil. Take a sheet up to 25 cm in size and fold it several times. Then start cutting it.
3. Glass jar or bottle. If you want to sharpen small scissors, you can use the neck of a bottle. Place open scissors into the neck of the bottle and begin to carefully connect the rings.
4. Cutting a sewing needle. It will help sharpen your nail scissors.

How to use the tool correctly

In order for the presented instrument to retain its sharpness for a long time, you should adhere to some recommendations.

1. If you use scissors to cut fabric, then use the tool only for this purpose. Then you don’t need to use it to cut fish, cardboard and other objects.
2. Other scissors are used to cut zippers and metal threads.
3. If you use them for cooking, caring for plants and nails, then disinfect them regularly.

The main thing is not to boil the scissors, but treat them with a simple antiseptic. Otherwise, they will quickly become dull and rust. Don't forget to lubricate them every six months.
