How to quickly sharpen scissors

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

In terms of benefits, scissors can only be compared to a knife. They can be of different sizes, used for different tasks, but one thing does not change - sooner or later they lose their former sharpness. Today we will talk about how to sharpen scissors and in what ways this can be done.

Difference from a knife

The knife has only one edge, which does the cutting. Therefore, sharpening is done at the smallest angle possible, so that the edge on its outermost part is as thin and sharp as possible.

In this regard, the technology for sharpening scissors is slightly different. This is because there are already two cutting surfaces that make an indirect cut. This works on the difference in pressure, which is applied by different sharp surfaces in opposite directions. Therefore, the knife is sharpened at an angle close to 90 degrees.

Where to start

In this regard, scissors are better compared to skates than to conventional knives. If you look at them from the point of view of the latter, then scissors, in principle, should not be sharp. It sounds strange, but it's true. What is more important here is the sharpening structure, in which the surface is sharpened evenly and uniformly.

If your scissors become bad at cutting even a simple sheet of paper, you need to first of all pay attention to the cutting edge and check it for damage.

In addition, before you start thinking about how to sharpen scissors at home, check their entire design. First of all, this concerns the hinge unit. This is the small screw that connects both parts of the scissors. Most often, this is a screw, and if it becomes loose, thereby impairing the functionality of the scissors, tighten it.

There may be a rivet in its place, which can also become loose. In this case, it needs to be crimped again, thereby returning the halves of the scissors to the desired state. In this matter, the main thing is not to go too far - if the screw or rivet puts too much pressure on the moving parts of the scissors, they will also work poorly.

Modern models of scissors are equipped with Ring Lock technology, which replaces traditional screws and rivets. If you have scissors with just such a mechanism, you don’t have to think about loosening this part.

Appearance

Next you need to look at the scissors from the side. Call it a master class for beginners on how to sharpen scissors, but many who criticize the sharpness of the blades simply do not look at their overall condition.

If the moving part of the scissors is bent, then no amount of sharpening will help them. This is very easy to determine - if, looking at them from the side, you see that any of the halves is curved, you can forget about their sharpness for a while.

Now the main task will be to align them. The slightest bend will be enough to disrupt the functionality of the scissors. It is equally important to be careful in this matter, because if you apply too much force, you risk breaking the item.

Cutting edge

It often happens that people quickly begin to worry about what can be used to sharpen scissors well, at the same time forgetting to even inspect the blade they are going to work with. It happens that small irregularities – jagged edges – form on the blades. Because of them, contact between two parts occurs, which disrupts the cutting properties of the scissors.

By removing this unevenness, you will again have working scissors at your disposal. In addition, scissors may simply rust. This also happens, and sharpening will not help them in any way.

First you will need to get rid of corrosion, and only then start sharpening them. To this same point I will include banal dirt and residues from cut objects, which are often small pieces of tape that get stuck between the blades.

Traditional methods

People always turn to this type of advice first. One way or another, the main thing is that the method works and helps you.

To start, you can take a simple needle, place it in the scissors as close to the joint as possible, then begin a cutting motion that will move that needle towards the end of the blades.

This method can help you get rid of small irregularities that have appeared on the edges of the blades and are preventing them from working properly.

Next, the folk instructions for sharpening scissors with your own hands proceed to simple foil. Many must have heard about this method before, since it is also very simple and very well known. Even old foil will do for this. You need to fold it several times, but not very tightly, and then start cutting it with scissors, which need to be sharpened.

The familiar dish sponge, made from metal shavings, works in a similar way. It is not necessary to sharpen the scissors on a new sponge, just take an old one that you are about to throw away - it is perfect for sharpening scissors. In addition to this, the sponge will also help you get rid of any excess dirt that may have remained on the scissors.

The situation is similar with sandpaper. To do this, you will need fine-grained paper that you can simply take and cut. Just as you usually did as a child, only now you will also sharpen the scissors.

Lastly, there is one more interesting and unusual method. We are talking about simple glass. First of all, you need to be very careful here.

Take a simple glass bottle of small diameter, good for some kind of sweet soda, and carefully start cutting it in the same way as described in the point with the needle - you should start from the screw and end with the edge of the blades. It is important not to overdo it with efforts so that the glass does not crack.

How to sharpen scissors at home

Many people try to find affordable ways to sharpen scissors instead of going to a professional sharpening shop or buying new tools. We'll tell you further how to do sharpening work correctly and what you might need for this.

What materials may be needed

There are proven methods for high-quality sharpening using a regular needle, an awl, a glass jar or bottle, foil, a special sharpener, sandpaper, a file, a whetstone, a sharpening machine, a paper clip, a battery and a screwdriver.

It is worth noting that there are subtleties when sharpening ordinary, kitchen, manicure, hairdressing, thinning, tailoring, gardening, sheep, non-separable scissors and those designed for metal work.

For ordinary scissors, it is better to take foil with sandpaper, for kitchen scissors - foil or a metal sponge, for manicure scissors - a special diamond file, for tailor's scissors - foil or sandpaper with a scratch pad, for garden scissors - a sharpening stone with a machine, for sheep - a machine with an abrasive wheel.

For metal scissors, it is necessary to maintain a certain sharpening angle. As a rule, it is selected only by a professional. To sharpen hairdressing and thinning scissors, you need laser and other equipment, since it is impossible to do everything efficiently at home.

They have special coatings that can be damaged quickly in real life. You need a special machine or purchasing new professional equipment from the appropriate store.

How to sharpen scissors correctly

Of course, you can sharpen scissors correctly and do it as quickly and efficiently as possible only in a workshop. However, this can be done just as well at home. The fastest way to sharpen regular and a number of other scissors that can be made sharp at home is with foil, a needle, or a metal sponge.

All that is required is to move back and forth at a certain angle. So, if the scissors initially had an angle of 30 degrees, then you need to sharpen them while maintaining the same angle. In this case, it is necessary to remove all sharp points and irregularities.

If there is rust on the scissors, you can use soda, vinegar, citric acid and peeled potatoes. After ridding them of corrosion, you need to go over them again with a metal sponge or sandpaper.

Attention! If you are unable to carefully sharpen scissors, especially manicure scissors, you should abandon the further idea of ​​using them.

You may receive wounds and abrasions. It is better to give it to a specialist for re-sharpening and try to correct the situation together with him. Otherwise, you need to buy a new pair.

You can sharpen scissors correctly by following the instructions presented above and using available materials. In the absence of a clear understanding of how to do this, it is best to contact a workshop for this.

How to sharpen scissors yourself

Over time, any scissors become dull and cut materials much worse. Don't rush to throw them away. Save on your purchase: restore the sharpness of the blades; fortunately, there are several simple and accessible ways to do this at home.

How and what to sharpen

The easiest way to revive office scissors and a hair clipper. With nail scissors the situation is more complicated: you will need a small block with a fine abrasive.

Advice
If scissors with curved ends become dull, it is better to buy new ones or contact a professional, as it will be difficult to sharpen them yourself.

Available sharpening methods:

• whetstone - sold in hardware and construction stores;
• foil;
• sandpaper;
• file.

Even though the blades are dull, they can still cut your hands. Therefore, it is highly advisable to work with protective fabric gloves and with care.

Special sharpener

A sharpening stone (a block, less often a circle) has two sides: low- and coarse-abrasive. We need to start with the last one.

How to operate the sharpener:

1. The stone is placed on a piece of cloth (to avoid slipping and damage to the surface) and lightly moistened with water.
2. The scissors are opened as wide as possible or disassembled - if the design allows.
3. Extreme care or experience is required when working with a whetstone. The most important thing when sharpening is to maintain the height of the blade angle. The factory tilt cannot be changed.
4. The blade is sharpened with movements in one direction (away from you). It is important that it goes completely across the stone, otherwise the scissors will cut the materials unevenly.
5. After sharpening on the rough side of the stone, the procedure is repeated on the fine-grained part.

Manicure scissors are sharpened according to the same rules, but on a special small sharpening stone. The best sharpening items are coated with diamond chips.

Tip
To check the sharpness of a sharpened object, cut a piece of synthetic fabric with it. This kind of material is quite difficult to cut. If it works the first time, the device is sharpened.

Foil method

This way you can quickly sharpen your manicure scissors.

How to properly sharpen scissors with foil:

1. A sheet of ordinary foil is folded in several layers - this way the effect will be noticeable faster.
2. The folded sheet is cut into several strips. The more there are, the sharper the object will become.
3. Remains of foil are removed from the blades with a dry cloth.

This method is an excellent preventive measure for scissors: as soon as they start to work worse, the blades are corrected by cutting the foil. This way you can also relieve stress.

Sandpaper

This is a quick method, the result is not the same as when using a sharpening stone, but the device will become noticeably sharper. The optimal abrasive is 150-200. With a finely abrasive sandpaper the process will take much longer. After working with the sanding sheet, wipe the blades with a napkin.

Three ways to sharpen scissors using sandpaper:

1. The sheet is placed on a flat surface. The scissors are opened or disassembled and the blades are moved in different directions, applying force. To prevent the sandpaper from slipping, it is secured at the edges with tape or something heavy.
2. The second way to sharpen an object is to move the paper itself along the blades.
3. If you don't mind, cut the coarse sandpaper with dull scissors. The optimal number of cuts is 20-25. The cutting process will make the blades a little sharper.

Advice:
Treat only the outer surface. If you grind the inside, the scissors will be damaged.

How to use a file

Sharpening scissors with a file takes longer than using other methods. To bring the blades into working condition using this method, it will take about an hour of continuous effort.

The device is fixed on a flat surface or held with one hand. The blades are alternately drawn along the file from the attachment point to the very tip.

You need a fine-grained file. As with the whetstone, you will need a steady and experienced hand. Sharpening is carried out at an angle made at the factory, and it cannot be changed during the process - otherwise the device will be ruined.

Sharpening scissors correctly is half the battle. The item must be used correctly: cut only what it is intended for, wash off dirt, wipe dry and store folded. Preventative home sharpening is carried out once every 2-3 months with regular use of the device. If scissors lie idle for a long time, they are sharpened once a year.

Often the reason for poor operation of the device is not due to dull blades, but to a loose fastening. Just tighten the bolt and the item will work like new. Another common reason is adhered dirt, glue from office tape, etc. You need to wash the blades with soap and a stiff brush, then wipe dry. Stubborn plaque is removed with soda, vinegar or alcohol.

How to sharpen scissors at home - proven methods and videos

This household tool is quite cheap (although there are also expensive scissors), but not every housewife would be willing to part with it and buy a new one. The explanation is simple - the force of habit. You can learn how you can sharpen dull scissors yourself at home from this article.

They are different - manicure, garden, household, stationery and so on. All differ not only in size, but also in the sharpening angle. And, nevertheless, the recommendations outlined in the article are equally suitable for any instrument, since its design is the same, regardless of specialization.

A fairly common reason why scissors do not cut material well is that the “halves” are loosened. If it is a screw, then you just need to tighten it. In the case of riveting, you will have to use a hammer and a small anvil. It is not difficult to determine what to use as a striker - a nail, a bolt or something similar.

It is better to tighten the halves when they are maximally opened. Excessive fixation often leads to the fact that they are locked tightly, and it is no longer possible to work with such scissors.

The second reason is that the ends of the blades do not meet tightly. This is easy to determine if you bring them together and see if there is a gap. If there is a significant gap, the limiter should be adjusted. This is a small protrusion on one (or both) rings. It's easy to sharpen it with a file.

If the free movement of the blades is limited, cutting the material is also difficult, and at the same time the housewife suffers from their sharpness. This “malfunction” can be easily eliminated by applying a drop of machine oil to the location of the fastener.

Sharpening rules

• All technological operations are carried out only in the “toward” direction (toward the rings).
• The factory sharpening angle does not change.
• To finalize the blades, only fine-grained abrasive is used.

Short-term recovery

There are situations when scissors are needed urgently, but it is impossible to cut the material efficiently with them. An effective way is to use the simplest devices.

• "Sandpaper." As already indicated, with fine “grain”. It is enough to make a few cuts on a piece of abrasive cloth, and you can work for a while.
• Needle. Naturally, a thicker product is taken. The needle is inserted between the blades, in the area of ​​the fastener, after which they compress/uncompress, gradually pushing it towards the ends. Two or three such “passes” are usually quite enough.

Sharpening with abrasive

Either a stone or a file is used. The basic rules have already been stated. It is necessary to maintain accuracy and uniform movement of the abrasive. The slightest distortion will lead to a change in the sharpening angle.

It is much more difficult if you need to sharpen the blades of nail scissors. They have a complex configuration, so it is better to process them with rounded stone. A file won't help here. As an option - a needle file (round or semicircular section).

Large tools (garden, metal) are pre-disassembled. The blades of such scissors are sharpened individually (usually with a file).

You can often find recommendations for processing cutting edges on an electric sharpener. If you have such experience, then the method is quite effective. But practice shows that, unfortunately, not every owner will be able to sharpen an ax or knife well on it. Therefore, this technique is not for “widespread use.”

What to consider

When sharpening blades, you do not need to strive to give them the sharpness of a straight razor. After assembling them, it turns out that they have limitations in use. For example, they won’t be able to cut thin fabric or paper, and it will be impossible to cut someone’s hair with them.

To prevent this from happening, an abrasive with a coarse “grain” is used for the main sharpening, and subsequent finishing is done gradually and finer, with periodic testing of the tool’s performance. If you can see that the blades cut well, then that’s enough. And it’s never too late to sharpen them additionally.

How to check the quality of sharpening? It is better to do this not on paper (dull scissors can cut it), but on fabric. If the blades don’t “chew” it, then everything is fine.

How to sharpen scissors at home

The most in-demand tool in the house is scissors. Various types of them are used in everyday life: tailor's, gardening, manicure, hairdressing and others. With frequent use, the blades become dull and a problem arises: how to sharpen the scissors yourself.

Recommendations for proper sharpening

Before you start sharpening, you must check the tool for defects. If the scissors do not cut the fabric, but only crush it, then the cause may be a loose fastening: a rivet or a screw.

A poorly tightened screw must be secured so that the blades fit snugly against each other. At the same time, you should not overtighten the mount, as your hand will quickly get tired during operation.

In addition, the screw must be turned no more than 0.5 mm. Otherwise, the mechanism may become stuck and cannot be repaired in the future.

If a rivet in the tool has loosened, then it is slightly flattened with a hammer. First, the scissors are opened as wide as possible and secured to the plane.

The edges do not close tightly. To correct the situation, you need to lightly trim the limiter, which is located on the inside of one of the rings, with a file.

Popular DIY sharpening methods

There are many ways to sharpen scissors using available tools:

• sewing needle;
• sandpaper;
• file;
• diamond wheel;
• special devices.

If there are no special sharpening devices, then you can quickly use a needle. Grab it with the blades and cut with some force. For these purposes, an iron rod or bottle neck is used. It will not be possible to achieve significant sharpness, but temporarily the tool begins to work.

Sandpaper with a grit of 150-200 or coarser abrasive is also suitable for sharpening. You need to fold a piece of emery cloth and cut it several times. In this case, the sheet should be facing outward so that the abrasive touches the blade. The paper is cut into strips along the entire length of the edge. The inner surface of the tool should not be touched, so as not to completely dull it.

Use sandpaper to remove any burrs or nicks that have formed. Steel wool and cloth sanding paper are used in a similar manner. After finishing work, wipe the blades with a damp paper towel to remove abrasive particles.

A sheet of aluminum foil (20-30 cm) is folded several times along its length until a thick strip is formed. Then, using the entire length of the blade, they begin to cut the resulting strip. The more sections you can make, the better the scissors will be sharpened.

Remove small foil residues on the blade with a paper towel. Traditional methods of sharpening scissors can only temporarily improve the situation or completely dull the tool.

Blades must be sharpened evenly at a certain angle, otherwise they will quickly become dull and cut poorly, jam and tear the material.

To obtain the desired effect when using ordinary household items, sharpening must be repeated several times.

Use of special devices

In order for the scissors to be sharpened efficiently, the top layer of metal should be removed until a sharp cutting edge is formed. This can be achieved using a machine on which the tool blade is rigidly fixed at a certain angle.

You can imitate a machine using a fine-grained sandpaper or sharpening stone. It is necessary to sharpen the entire plane of the edge at the angle that was set during factory stamping. This is done by moving the blade from the screw to the tip of the tip.

To make sharpening more efficient, the scissors are disassembled into their component parts in advance. During operation, you cannot change the angle of inclination. A simple and convenient tool for processing tools is a sharpener for knives and scissors, which can be purchased at a hardware store. The sharpener has special attachments that are used to sharpen blades.

Sharpening scissors for metal

Metal scissors are made of hard material, so the sharpening angle should be quite high: approximately 75 degrees. The blades of the tool are processed in the same way as ordinary scissors. Using a needle and fine-grit sandpaper you can sharpen quickly, but the effect will not last long.

Better sharpening is achieved by using a hard abrasive in the form of a file. The scissors are first disassembled into parts and one half is secured in a vice. In this case, the edge to be sharpened should be on top, with the tip “away from you.” The movements of the file “from you” are made slow and only in one direction. Sharpening is carried out until the blade becomes perfectly smooth. Then a similar operation is repeated with the second half of the instrument.

After finishing work, both blades are treated with an anti-corrosion compound, which allows you to extend the life of the scissors without sharpening. Next, the blades are connected, and the tool can be used.

How to sharpen a scalpel at home

Scalpels and other similar medical instruments are sharpened in the same way as knives, only at an angle of 15 degrees. To process them, whetstones, emery and carborundum wheels are used.

When sharpening a scalpel, certain rules are followed:

• tools need to be sharpened with the blade forward;
• both chamfers of the blade are processed evenly;
• it is necessary to strictly observe the sharpening angle, which should be two times less than the angle between the two sides of the edge.

Sharpening hairdressing scissors

The tool rings are securely fixed, opening the blades as much as possible. The sharpening angle should be 60−70 degrees. The file is passed several times along the inside of the blade from the sharp tip to the joint. It is not recommended to change direction when sharpening. Check the quality of work on thin polyethylene or oilcloth.

Thinning shears have a complex serrated blade with grooves that are designed to hold the hair while cutting. To sharpen them, you will need a professional machine with an angle adjustment, so it is better to give such a tool to a specialist.

When processing blades, you must follow safety rules - protect your hands with leather gloves. Children should not be allowed to sharpen on their own.

If you want your tools to last as long as possible, you need to use them strictly for their intended purpose. Thus, tailor's scissors are intended only for cutting fabric. For paper there are stationery, etc.

How to sharpen knives and scissors at home

Kitchen utensils are subject to frequent dulling, but it is not always possible or willing to buy new knives and scissors. The article will tell you about the method of sharpening sharp objects at home and will help solve your problem. Even if the tool is not sharp, it can still harm you, so it is better to carry out the procedure with protective gloves.

Preparation

Please note that stationery scissors lend themselves well to sharpening. It will be difficult to cope with manicures. Before you start repairing them, it is important to make sure that the problem lies in poor performance due to loss of sharpness, and not due to a poorly screwed bolt.

Rules for working at home

Before you get down to work, you need to know the rules that will help you sharpen your equipment more efficiently. It is important to remember that when turning tools, they sharpen towards themselves; every movement must be controlled by you. It is necessary to take into account a certain sharpening angle with which the tool has already been sharpened. There are many knives that are sharpened only at a certain angle, and another angle can completely ruin the tool. As you work, you are more likely to develop “burrs.”

You can remove them on the same grindstone, on the finely abrasive side. And finally, of course, you need to check the tools. They need to be checked against the materials to which the tool being sharpened belongs.

For example, if you sharpened hairdressing scissors, then you should check them on the hair. If tailors, then on fabric. You need to take a small piece of fabric and make an incision. If the scissors do not “chew” the fabric, but cut accurately and without tears, the work was done correctly.

And with knives it’s much easier; checking on vegetables will speak for itself.

Grindstone

The fastest and most effective method that even a housewife can do, but this procedure must be carried out using a special technique. In order not to damage the tools, especially if you are new to this business, practice on other knives before carrying out the procedure.

The sharpening stone has two sides: low- and coarse-abrasive. You need to start the procedure with a coarse abrasive. Sharpening instructions:

• Place the stone on a fabric surface so that it does not slip.
• The scissors should be opened as wide as possible. The knife should slide tightly on the sharpener.
• The blade must be sharpened in one direction (away from you). Don't miss a moment and make sure that the blade goes completely over the stone.
• After this, repeat the procedure on the other side of the sharpener.
• The sharpening degree of the tool is up to 70-75.

Of course, there are not many ways to effectively revive suddenly dull knives and scissors. Some will prefer not to bother and go buy a new knife in the store, while others will still try to sharpen it themselves. Not all methods are as effective as you imagine, however, with the right sharpening technique, you are guaranteed to get good, sharp tools.

Basic rules for sharpening

To avoid common mistakes and sharpen, you need to perform a number of steps correctly. During the procedure, the following points must be taken into account:

• when sharpening, it is recommended to move towards yourself, from the end to the rings;
• you cannot deviate from the production sharpening angle, which varies between 60-75 degrees.

Available methods at home

At home, you can effectively sharpen a tool using available tools. It is worth familiarizing yourself with all the possible options and choosing the one that suits you.

Foil

A sheet of foil can be used regularly to maintain a sharpness or for a full sharpening. To do this, fold the material in several layers to form a dense strip. The material is cut, and then the remains are removed from the blades using a napkin. For constant use, it is enough to make several thin strips of foil.

File

You can sharpen scissors with a file by running the blades along the work surface. It will take about 20-30 minutes to complete the procedure. After finishing sharpening, you need to wipe the blades to remove any chips that have formed.

Gypsy needle

You can sharpen the scissors with a gypsy needle, placing it between the blades as close as possible to the screw. Then they press the blades on the needle, trying to push it up. This effect promotes accelerated and uniform sharpening. It is important to consider that this method helps no more than 3-4 times, after which you need to sharpen the device in the workshop.

Jar

A transparent jar made of thick glass is also suitable for use as a tool for sharpening scissors. The blades of the scissors are opened so that the can can fit between them, and then the cutting action is performed. In just a few minutes, glass will help restore the original sharpness. To perform the procedure, it is better to use an unnecessary jar, since scratches and chips will remain on its surface.

We sharpen different types of houses

Milled

It is almost impossible to restore the sharpness of milled scissors on your own. To sharpen the blades, it is better to go to a workshop.

Cuticle nippers

Miniature nippers are easy to sharpen using foil, sandpaper or a file. It is important to be especially careful not to damage fragile elements.

Manicure

Manicure tools are sharpened according to a standard pattern. The peculiarity lies in the need to remove backlash, which is often present even with a new tool. Otherwise, the cutting parts will not converge correctly.

Tailor's

It is better to sharpen scissors used by tailors using specialized equipment. When performing the procedure at home, it is important to be careful.

For metal

Metal scissors are easily sharpened with a needle and sandpaper. A more effective way is to use a vice and abrasives.

How to properly sharpen scissors at home: sharpening angle and features of using the tool

Scissors are a necessary thing for tailors, hairdressers, shoemakers and other craftsmen. But you can’t do without them at home either. Gradually, the device begins to cut worse and becomes dull.

You can buy new scissors or take them to a workshop for sharpening. Only there they can do it efficiently. But if there is an urgent need to restore the sharpness of the scissors, you can resort to several home methods. It is important to take into account that they will only temporarily correct the situation and in the future it is better to take the scissors to a specialist for sharpening.

articles:

General rules

If the device begins to cut poorly, you need to figure out whether the problem is really dull blades. The fastening may be loose, causing the blades to fit poorly and not cut. You just need to tighten the thread and the problem will be solved. It is necessary to check whether the tips of the blades meet each other. If there is a distance between them, use a file to sharpen the stops near the rings. If everything is fixed, but the scissors still cut poorly, you should sharpen them.

It is important to sharpen scissors correctly so as not to dull the device further:

• Do not change the production sharpening angle.
• The sharpening procedure is carried out in the direction from the nose to the rings.
• At the end of sharpening the blades, you need to sand them to remove burrs.

You can check the quality of sharpening by making a couple of cuts on thin fabric. The cut should be smooth.

DIY methods for sharpening scissors

If there is no good craftsman nearby, and there is no way to buy new scissors, then you can temporarily revive them using improvised sharpening tools.

Sandpaper (sandpaper)

It is desirable that it has a fabric base and a grain size of 150 or more. Fold the sandpaper in half with the abrasive facing out. Start cutting the sandpaper. The abrasive will touch the blades and sharpen them. You need to make 10-20 stripes. You need to cut along the entire length of the blades.

On a note! You can also use sandpaper to remove nicks on scissors. This sharpening method is not suitable for very dull instruments. You can only sharpen it a little with sandpaper. Finally, wipe the scissors with a damp towel. An alternative to sandpaper is a metal kitchen sponge.

Glass jar

Take an unnecessary jar that you won’t mind throwing away. Insert it between the scissors blades opened to their full width. The jar needs to be brought as close as possible to the center of the tool. Hold the jar in one hand and the scissors in the other. Close the scissors by sliding the blades along the surface of the container. It will move out. You need to make every effort to ensure that the glass sharpens the cutting edges as best as possible. After the procedure, wipe the blades with a damp cloth.

Pins

They are used according to the same principle as in the previous methods. Place a sewing pin between the blades. Close them, moving the pin from the middle outwards along the cutting surfaces. Sharpen until the scissors are sharp enough.

Touchstone (grindstone)

It can be purchased at any hardware store and can be used to sharpen many cutting devices. As a rule, the whetstone is double-sided - with a fine-grained and a coarse side. It is better to start sharpening dull scissors with a rough surface and finish with a fine-grained one.

Place the whetstone on a towel and cover it with special oil for honing (can be water or any other oil). Unscrew the screw in the scissors that holds the halves together. It is better to sharpen the blades separately.

First, the inner surface of the blade is sharpened. Place its inner side (the one adjacent to the second blade) on the whetstone. Set the correct angle between the inner blade and the cutting edge. You need to sharpen the line of contact between the two edges. Take the blade by the handle and slowly move it along the whetstone. The edge of the blade must not be torn off the surface. You need to hold it horizontally away from you. Repeat the action 10-20 times. Do the same procedure with the second half of the scissors.

When working with a whetstone, you must first practice sharpening correctly on old scissors until you develop certain skills.

• Do not boil the device in order to disinfect it. This will lead to rust. It is better to treat the instrument with an antiseptic.
• Once every six months, lubricate the layout mechanism with oil.
• It is advisable not to disassemble the scissor mechanism unless necessary. Some items cannot be reassembled.
• Use scissors only for their intended purpose.
• Choose the correct angle for sharpening the blade. Otherwise, the scissors will stop cutting.

If your scissors become dull, you don’t have to immediately go to the store for new ones. You can revive a tool by sharpening it. It is best to do this in a special workshop. If you need to sharpen scissors quickly at home, you can resort to several simple methods, but all of them have only a temporary effect. It’s still better to find an opportunity to have the device sharpened by a professional.

If your favorite scissors become dull, you don’t have to run to the professionals for help. You can sharpen the tool yourself. There are many ways to do this.

Fine-grained grinding wheel or emery stone

You can quickly sharpen scissors using a whetstone or wheel. The procedure is carried out on the coarse abrasive side.

The process consists of the following steps:

1. A stone is placed on a piece of cloth and slightly moistened with water.
2. The scissors are taken apart or opened very wide.
3. Draw the blade forward with force and back without pressure. At the same time, it must completely pass over the stone, otherwise the scissors will cut unevenly.

The plane of the sharpened part must be located away from you. After this, the procedure is repeated on the fine-grained part. Check the sharpness on the fabric. If the scissors cut without zeal, then the object is sharpened well.

Cutting foil folded in several layers

Every woman has foil in her kitchen. It is with its help that you can easily sharpen dull scissors. To do this, it is folded in several layers and cut into many strips. The more there are, the sharper the scissors become. After completing the procedure, remove the remaining foil from the blades with a dry cloth or napkin.

Cut sandpaper

To quickly restore the sharpness of the blades, use sandpaper. You will need fine-grain sandpaper. The optimal abrasive is 100–250.

There are several ways to sharpen:

1. The sandpaper is folded in half and cut with scissors into several thin strips.
2. The paper is secured to the table with tape. The scissors are opened wide and the blades are drawn in different directions, applying force.
3. They take the paper in their hand and simply move it along the blades.

To check the sharpness, cut a napkin or fabric. Processing is carried out only on the outside and in no case on the inside, otherwise the scissors will be damaged.

Cutting metal kitchen sponge

If you urgently need to sharpen an object, a regular metal sponge works well. To do this, take it in your hand and carefully cut it into small pieces with scissors until the blades become sharp. The procedure is carried out over a trash can, since this method has one big drawback - a lot of small metal debris.

You can straighten scissors easily and simply at home, using improvised means. The main thing is to choose the appropriate sharpening method and follow all the rules.

How to sharpen scissors at home

Good, sharp scissors make nice, clean, precise cuts. Their frequent use requires constant sharpening of the blades. This applies not only to kitchen tools for cutting bones and tendons, but also to scissors intended for sewing and household needs.

Sharpening can be quickly done by a specialist with special software, but it costs money. In addition to the cost, you will have to wait for your instrument to be returned.

There are several ways you can easily sharpen your own scissors at home using household items.

1

How to sharpen scissors - use a sharpening stone

The most effective and traditional method of sharpening scissors is with a whetstone or stone.
They can be purchased at a hardware store. Any flat stone from the yard will not work for this purpose.

If possible, purchase a multi-grade surface grit for more precise sharpening. Apply lubricating oil to the sharpener. Disassemble the scissors if possible. This will make sharpening easier and more efficient. If the scissor blades do not separate, open them as wide as possible.

Sharpen the cutting tips on each side. Try to keep the blade exactly diagonal to the stone.

Place scissors away from the sharpener for your safety. Repeat the procedure with the other blade. Open and close the scissors several times.

2

How to sharpen scissors on glass

All you need is an empty glass bottle.
You can also use any type of jar. This method will seem a little awkward at first, but you will soon get the hang of it. Open the scissors as wide as possible around the bottle. In other words, act as if the scissors were cutting the object into two parts. This will sharpen the blades from the pivot point to the tips. Repeat as needed.

The method using household aluminum foil or sandpaper may seem mediocre.

Pull the foil from the roll and fold it in half several times. Insert the foil to the turning point and cut slowly. Repeat as many times as necessary until the knives are smooth.

4

How to sharpen scissors - steel wool

Steel wool, which we use to clean household dishes, can also sharpen scissors perfectly. Use it to cut across the surface several times, making sure to use the full length of the blades. Repeat as needed.

5

How to sharpen scissors with a screwdriver

Essentially, you are repeating the same technique described for glass bottles. Open the scissor blades and insert the metal shaft with a screwdriver at the pivot point. Close the scissors as if you were going to cut with a screwdriver, and then repeat several times.

6

How to sharpen scissors - use a cup

You can sharpen dull scissors using a regular cup. Turn it upside down and move the blade of the tool towards and away from you.

The more time you spend on your scissors, the sharper they will be and the longer they will last.

8 ways to quickly sharpen scissors

Eight different ways to quickly and easily sharpen your scissors without having any special tools or equipment. In fact, we will use available items that will help the scissors regain their former sharpness and cut as before.

1. Sharpen scissors using a paper clip

Take a regular metal paper clip. The larger its size, the better.

The sharpening technology is as follows. Use scissors to pinch the tip of the paperclip.

And, slightly squeezing the knives of the scissors, draw a paper clip until the knives intersect.

Next, remove the paper clip. We repeat these steps 30-40 times. Corresponding notches appear on the paper clip.

2. Use the battery case

For sharpening, you can use a AA battery, but always in a metal casing.

We do all the sharpening steps in the same way as in the example with a paper clip. Movements should be made from the tip of the scissors to the intersection.

3. Using sandpaper

In this example we will use sandpaper. The smaller its grain size, the better. It’s better to take “zero”. Everything is very simple here. Cut it into thin strips. At this time, sharpening of the blades occurs. Don’t forget to turn the paper over to the other side so that the knives are sharpened evenly, or simply fold it in half.

After this, cut the napkin to smooth the surface.

4. Glass sharpens scissors

Any glass is considered a very hard material. We take a glass bottle and sharpen the blade on its neck. There should be notches on the bottle.

Be careful as the glass will crumble.

5. Use foil

We roll up regular food foil into 4-8 layers. Just like in the example with sandpaper, cut the foil into thin strips.

40-50 cuts should be enough.

6. Using a screwdriver

Take any screwdriver and press it into a hard surface. We clamp the screwdriver shaft with the tips of the scissors and, with a little force, move the scissors apart. We repeat the operation 30-40 times.

7. Sharpen with a file

We clamp the scissors in a vice in an open position to the maximum.

Using a file, we pass along the cutting edge from the middle to the tip.

We sharpen each side separately. Instead of a needle file, you can use a whetstone.

8. Cutting metal sponge

You can also sharpen scissors by simply cutting a metal dishwashing sponge.

After sharpening the scissors, be sure to remove wear products: metal shavings. It would be a good idea to lubricate the blades.

How to quickly sharpen scissors at home

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. This includes not only household, stationery, hairdressing and tailor's scissors, but also their home varieties such as garden 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.

How to sharpen scissors at home video

Even the best quality scissors become dull over time, but it is not always possible to go to a sharpening workshop. Therefore, the question of how to sharpen scissors at home is relevant in such cases. Having certain skills, you can correct the blades yourself.

Why don't they cut

Before you start sharpening, you need to identify the reason why the scissors stopped cutting. There is a situation when the blades are still quite sharp, and it is almost impossible to process fabric or paper with them. The reasons may be:

1. Loosening the fastening bolt. In this case, it is enough to tighten it a little tighter. It should be taken into account that tight blades will complicate operation - your hand will get tired. It is better to tighten the instrument when it is fully opened.
2. A gap appeared between the ends. When you try to cut thin fabric, it will only become pinched. To eliminate the gap, you need to adjust the stop heel near the hole with the bolt. You cannot bend the blades to better fit each other - the tool will no longer work, as it will deteriorate. The gap between the blades should be less than a tenth of a millimeter.
3. The blades have become dull. Only sharpening the scissors will allow them to be used further.

To properly sharpen scissors, it is necessary to determine the factory straightening angle. This will help to carry out work more efficiently and increase the service life of the tool. It is known that the size of the corners is made depending on the functions of the device.

The sharpening angle of scissors is determined by the following rules:

1. For cutting soft materials - paper, fabric, it is usually maintained at 60 degrees.
2. If you need to cut something harder - 70-75 degrees.

If the blade is tight, cutting the material will also be difficult. This problem can be easily corrected by dripping a little machine oil onto the area where the parts are held together.
