How to sharpen scissors at home - tips for a master
All cutting tools need to be sharpened periodically. There are several ways to sharpen scissors at home. The choice of method depends on the type and purpose of the device and the type of malfunction. Having determined why the tool is not working well, you can begin to correct the defect.
Types of scissors
Scissors are everywhere. They are gardening, tailoring, manicure, hairdressing, kitchen and others. There is a tool for cutting metal and metal tiles. The main feature of scissors is the blades. They use a type of cut between edges. The cut is made with two blades, so they are sharpened differently than knives that have only one blade.
The sharpening angle of a tool for paper or fabric is 60° , and for harder materials it is increased to 70-75°. The smaller the angle, the sharper the blade, but reducing the angle leads to rapid wear of the tool. You cannot change the factory sharpening angle: this will lead to damage to the tool.
Home sharpening methods
If the scissors begin to cut poorly, you need to check the hinge assembly. The halves of the instrument must be securely fastened. A loose fastening makes it impossible to operate the scissors correctly. Fastenings can be rivet or screw. You can tighten the fastening screw with a screwdriver. If the fastening is rivet, then you need to crimp the rivet.
Then you should check the cutting edges and inspect them for nicks. One notch can separate the blades and interfere with the operation of the tool. There is often dirt on the surface of the blades. Before sharpening, you need to clean them with alcohol or solvent. After the preparatory work, if the functionality of the tool has not been restored, you must begin sharpening. To sharpen scissors with a needle, you need:
- Choose a needle made of hard metal.
- Open the tool, place the needle close to the hinge and try to cut it.
- The needle should move towards the ends of the blades.
- Repeat these steps several times. As a result, the tool should become sharp.
A good way to sharpen scissors at home is to cut aluminum foil. You need to fold the food foil several times and cut it into small pieces. You can also use fine-grit sandpaper. In order to sharpen scissors at home correctly, you can use a glass bottle, trying to cut its neck. You can buy ready-made sharpening devices, but they are only suitable for one type of tool.
Working with a whetstone
There are many different sharpening stones available for sale. One side is fine-grained and the other is coarse. You need to use the rough side first. Procedure:
- Place the whetstone on a cloth and moisten it with water.
- Open the blades wide.
- You only need to sharpen the tool in one direction, from the tips to the rings towards you. It should be remembered that under no circumstances should you change the angle of the factory sharpening.
Repeat these steps on the fine-grained side. Sand the blades with fine sandpaper to remove small burrs. On a whetstone, in addition to scissors, knives and other tools, you can also sharpen a scalpel at home.
Application of grinding machine
The use of an electric sharpening machine allows you to sharpen the tool most accurately. The guide must be set at the desired angle. The direction of rotation of the circle is towards the edge of the blade. It is enough to pass the blade 2-3 times for complete sharpening.
You can make a device for fixing the scissors at a certain angle. This will improve efficiency and perform the operation multiple times. There is no need to straighten the tool after the sharpening machine.
If transverse serrations have formed on the blade, you can leave them: they help cut hard materials.

How to sharpen scissors at home
Scissors are one of the most common types of household tools. This is explained by the fact that they are used both for household purposes and in professional activities. But the work of the scissors will continue only as long as the cutting edges remain sharp. Dull blades will not allow you to make a normal cut even on the most pliable material. How to sharpen scissors at home, without turning to specialists? We talk about this in this article.
Preparation for sharpening
Unsatisfactory cutting can be caused by more than just dull cutting edges. Loosening of the center tie bolt or rivet causes a gap to form between the blades, which impairs the performance of the scissors. Such a defect must be eliminated and then the cutting ability of the tool must be checked again.
Poor cutting can also be caused by contamination on the blades left after processing certain materials. They can be removed using cotton wool or a soft cloth soaked in alcohol or technical solvent. Sometimes such layers may not be visible due to the transparency of the composition, and therefore wiping before sharpening is recommended in any case.
Sharpening using improvised means and tools
There are several ways, based on folk experience, on how to sharpen scissors at home. You do not need a special tool, but only simple available tools. Of course, there are sharpening devices and machines, but they are mainly used when it is necessary to restore the sharpness of blades on professional scissors.
Smooth metal rod
This is the most affordable way to sharpen scissors at home. You will need any small diameter steel rod with a smooth surface. This could be a gypsy needle, an awl, a screwdriver, a pin, or even a simple paper clip.
A little worse, but still possible, is to use a round AA or AAA AA battery.
Spread the scissors so that the rod fits as close to the pinch bolt as possible. After this, lightly pressing the handles, begin to bring the blades together, and move the tool you are using away from you towards the cutting ends. Perform these steps 10-15 times and check how the paper is now cut. If the result is still unsatisfactory, repeat the operation again.
Porcelain cup
Most tea cups have a smooth abrasive surface on the outside of the bottom. It can be used instead of a special sharpening stone.
Open the scissors as far as possible. Apply the bevel of the blade at the top to the edge of the cup and, pressing lightly on it, move it along the abrasive towards you. The movement when sharpening should occur only in one direction, otherwise you may not sharpen, but completely and completely ruin the tool.
Aluminum foil and sandpaper
Probably every housewife has foil in her kitchen for baking food. Take the roll and tear off a piece 20-30 cm long from it. Fold it lengthwise 6-8 times to get a dense multi-layer strip. After this, start cutting the foil lengthwise, using the entire length of the blades. After 10 cuts, check the sharpness and, if necessary, repeat the steps.

How to sharpen scissors: methods for sharpening at home, their features
Scissors are an important and almost irreplaceable household appliance. There are two main types: stationery and manicure. The service life of the product depends on the quality of workmanship and the type of metal used. Almost any scissors require periodic sharpening. You can cope with the task of sharpening scissors at home using various methods.
With constant use, office scissors need to be sharpened no more than once every 6 months. Do not forget that sharpening a metal product involves removing a layer of material, which reduces its service life.
Due to the use of low-quality mild steel, scissors produced by little-known manufacturers become dull quite quickly . The mechanism for fastening the two parts of the structure has relatively low strength and can quickly break under significant mechanical stress. More expensive and high-quality products can last a long time.
There are quite a large number of different methods for sharpening scissors. The most common are:
- Using a needle.
- Using sandpaper.
- Removing metal using a file.
- Application of a diamond wheel.
- Using a special device.
The features of the method used only partially affect the quality of sharpening. As a rule, when using a special device, the process is significantly simplified and accelerated. to carry out the procedure several times to achieve the desired result .
Preparatory stage
You can sharpen scissors at home in the shortest possible time. In order to improve the quality of the result obtained and eliminate the possibility of complications of the process, attention should be paid to the preparatory stage:
- All contaminants must be removed from the metal surface being treated. To do this, simply moisten cotton wool in alcohol and wipe the surface. In some cases, more serious contamination occurs, for example, paint. You can get rid of them by combining mechanical and chemical surface treatment methods.
- The tool is checked for the presence or absence of defects. Many people decide to sharpen their scissors because they are not cutting well. In some cases, the problem may be that there is a large gap between the two halves. If the ends do not meet, then the problem is with the mounting screw.
If the connection of the two halves is loose, you can tighten the connecting mechanism using a screwdriver and pliers, as well as a hammer. Both a screw and a rivet can be used as a connecting element. When performing such work, the following points should be taken into account:
- The mechanism should be tightened carefully, as if the clamp is too strong, the scissors may become stuck and will have to be thrown away.
- It is recommended to turn the screw no more than 0.5 mm.
- In the case of a rivet, the scissors are placed on the anvil and fixed; with a few blows, the plug can be flattened.
- Some models have a kind of limiter that prevents the two halves from meeting. In order to reduce the gap, the limiter is filed down.
After eliminating the defects, you should check whether sharpening is required . Very often the cutting edge is in good condition, but due to the large gap, the scissors cannot cut materials.
In most cases, it is necessary to sharpen the scissors if there are no special tools at hand. The way out of this situation is often to use a regular needle.
This method of sharpening a metal product involves performing the following work:
- Stretch the two halves as wide as possible.
- The needle is placed near the section.
- The two halves of the scissors are gradually brought together. Naturally the needle moves forward.
It is recommended to repeat this procedure 2-3 times . When making a needle, hard metal is usually used. Upon contact with the cutting edge, a layer of metal is removed from the surface being processed. Naturally, the needle is positioned at the desired angle relative to the cutting edge.
Using Sandpaper
You can also quickly sharpen scissors using sandpaper. To carry out the work, you only need paper with any size of abrasive. The sharpening process in this case is quite simple.
A sheet of sandpaper should be folded in half. The abrasive surface must be outside .
The folded paper is placed between the two separated parts of the scissors, after which several cuts should be made.
This method is only suitable for cases where there is not enough time to fully sharpen the surface. After some time, the cutting part will become dull again.
A file is a tool designed for removing metal from various surfaces. When you need to sharpen hairdressing scissors, the conventional method is not suitable. Sequencing:
- The scissors are being prepared for the work being done. Various contaminants should be removed from the surface, for which you can use cotton wool soaked in alcohol.
- The two halves should be placed as far apart as possible. In order to eliminate the possibility of changing the sharpening angle at the time of processing, the rings should be fixed with your fingers.
- To sharpen, you need to process the inside at an angle of 60-70 degrees.
- The file should be flat and have no worn parts on the surface. Otherwise, the processing quality will be poor. When the tool is sufficiently pressed against the surface being processed, you need to move it several times towards you from the beginning of the blade.
When using a file, the surface should be sharpened in only one direction .
Application of diamond wheel
If professional instruments are not available, the processing can be carried out using a diamond wheel. This method is more suitable for processing small or fragile items. Its features include the following points:
- You should work with a diamond wheel carefully, as mistakes made can cause a change in the sharpening angle. If you change the sharpening angle, the scissors will become unusable.
- It is recommended to set the device used to minimum speed. Sharpening should be done smoothly starting from the tip. Do not press too hard on the workpiece.
- It is not always possible to sharpen the blade in one go. Processing is carried out until the required result is achieved.
Instead of a diamond wheel, you can use a diamond nefil . To sharpen nail scissors, you should use two types of diamond nefil: first, processing is carried out with a coarser grain, then with a fine-grained tool. By using abrasives with different grain sizes, you can achieve better results.
Other recommendations
You can find just a huge number of different recommendations related to the processing of nail scissors. In order to significantly increase the service life of the product, you should pay attention to the recommendations below:
- Do not boil scissors for the purpose of disinfection. This kind of impact causes active formation of corrosion on the surface. Inexpensive disinfectants can be purchased to kill germs.
- It is recommended to treat the scissors layout mechanism with oil once every six months. To extend its service life, just a few drops are enough. Oil not only reduces wear on the damaged element, but also prevents the formation of corrosion.
- It is not recommended to disassemble the scissors, since many mechanisms cannot be reassembled.
- The product should be used exclusively for its intended purpose. In other words, hairdressing scissors cannot be used to trim plant branches.
- You cannot grind metal over the entire surface. If the sharpening angle is observed, the service life of the product can be significantly extended.
Thus, sharpening of professional tools should be carried out by a professional . An example is thinning scissors, which cannot be sharpened at home using conventional tools.

How to sharpen scissors without a sharpener
8 ways to quickly sharpen scissors
Inventors shop at a budget Chinese online store.
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.
DIY electronics in a Chinese store.
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.
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.
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 properly sharpen knives on a machine
> Knife sharpening
04.08.2019
The sharpness of the knife affects the speed of work performed and ensures the safety of users. It is achieved both mechanically and through the use of motorized devices. The second option makes it easier to restore the cutting edge. But working on the equipment is impossible without knowledge of how to properly sharpen knives on a sharpening machine.
Sharpening or straightening knives
Before returning the knife blade to its original state using an electric sharpener, it is necessary to determine what actions are required for this tool - sharpening or straightening. When using a blade, the tip is often damaged and deformed.
It forms:
- edge bend;
- chips;
- wavy surface.
Electric knife sharpener.
Removing defects on a grinding machine will require the use of different attachments and changing the rotation speed. Otherwise, you can cut off the excess layer of metal. To avoid this, you must first straighten the tool using mechanical straightening using a tool in the form of a round file (musat). It has a special surface made of durable steel, ceramics or diamond chips. The device is suitable for removing the bend of the blade at the edge.
Experienced craftsmen sharpen blades on a sharpening machine at minimum speed. The wave-shaped deformation is cut off completely. There is no other way to remove it. Chips should be removed in the same way. Then you need to start sharpening the tip.
Grinding knives on a machine
Grinding is the final stage in sharpening blades. When the blade is brought to the desired sharpness, burrs appear. They are removed by processing the tool on a nozzle with fine abrasive crumbs. Then they transfer to a felt disc with the application of a special GOI finishing paste. The knife is polished until absolutely smooth.
Electric knife sharpeners
Modern electric sharpeners are a design with an electric motor, on the axis of which abrasive discs coated with diamond are located. The components of the sharpener are placed in a closed housing with slots for the blades. There are models in which the angle of the blade is set automatically.
Electric sharpeners have the following advantages:
- compact dimensions;
- availability of sharpening and polishing modes;
- connectors for different types of knives and scissors;
- safety at work.
Before using the sharpener, you must read the instructions, which include:
- device description;
- work rules;
- sharpening direction;
- recommended implement angles.
To add sharpness, the blade must be inserted into the hole of a working sharpener and pulled towards you. The number of repetitions depends on the degree of edge wear (from 5 to 10). The blade is then polished.
The disadvantages of an electric sharpener include its relatively high price. It must be remembered that tools sharpened with this equipment quickly become dull.
How to sharpen knives on a machine correctly
A sharpening machine is an electrical device with abrasive attachments that differ from each other in the size of the granular chips.
Before working on the sharpener, consider the following points:
- knife functionality;
- metal quality;
- sharpening angle;
- rotation speed of the nozzles.
Knife sharpening machine.
All points are interconnected. The value of the sharpening angle before polishing the object depends on the cases in which this or that tool is used:
- 10-17° - for thin tools (razors, scalpels). These items are treated only with fine-grained nozzles operating at reduced speed. With a minimum sharpening angle, the edge is the sharpest, but such objects become dull faster.
- 20-25° - for kitchen knives. Small tools with a thin blade can be irrevocably damaged by a rough abrasive wheel. In this case, a fine-grained disk with a low number of revolutions is used.
- 25-30° - for tourist and hunting blades, which are made of durable Damascus steel. Kitchen cleavers used for cutting meat and chopping bones are also sharpened at this angle.
- 30-40° - for rough tools, the use of which makes work in the garden easier, and for tools capable of cutting carpet, hoses, and cardboard.
On modern industrial sharpening machines there are no problems with maintaining the sharpening angle: the knife is inserted into special openings and secured. The fixed position allows you to sharpen the blade symmetrically on both sides.
It is difficult to measure the angle at home. Experts advise focusing on the width of the eyeliner (the size of the cut from the edge to the entire area). For kitchen blades it is 2-3 mm, for rough tools (an ax, scissors for gardening) - from 4 to 5 mm. If the knife is sharpened correctly, the eyeliner will be the same along its entire length.
On an emery machine
An electric sanding machine is a necessary item in the household. Use it to sharpen any cutting objects. The kit includes abrasive discs with coarse and fine crumbs.
Sharpening knives on an emery-type sharpening machine follows the following algorithm:
- The blade is applied with its edge to the rotating coarse-grained disk from the side.
- The blade must be tilted to the required degree.
- Run the edge along the disc from the base of the handle to the tip, without changing the inclination or direction.
- The movements are repeated on the reverse side of the blade.
- The number of repetitions should be the same on both sides.
- You need to sharpen until burrs appear.
- The roughness is carefully removed.
- The blade is edited using a fine-grain attachment, alternately on each side.
To sharpen the tip evenly, you need to move it smoothly and without strong pressure along the side of the nozzle. If this is done slowly, the blade will overheat and the edge will become damaged.
On a machine with an abrasive wheel
A machine with an abrasive wheel, or grinder, is used for sharpening knives and tools, which allows amateur craftsmen to save on purchasing an electric sharpening machine.
To sharpen the blade, the grinder is strengthened with the disc facing up. During work, nozzles with medium and fine abrasives are alternately used. The sequence of actions is the same as when working on sandpaper. It is important to take into account the rotation speed of the grinder’s nozzle, which reaches 11 thousand revolutions per minute at minimum power. Therefore, before you start sharpening, you need to understand the nuances and practice in the presence of an expert.
Tips from experts on sharpening knives on a machine
When working on a sharpening machine, expert advice will come in handy:
- To avoid overheating of the knife blade, you need to use sharpening machines at low speed.
- If it is impossible to reduce the rotation speed of the nozzles, you should keep a container of cold water nearby to periodically cool the heated object.
- Do not check the sharpness of the blades with your fingers: this can lead to cuts and infection. In such cases, tests with a sheet of paper or a tomato are used.
- During sharpening, metal particles and crumbs bounce off the nozzle. Therefore, experts recommend using protective equipment (glasses, long sleeves, gloves).
- In order for knives to remain sharp for a long time, they must be stored correctly: placed in separate wooden holes or on a magnetic panel.
- Use sharp tools for their intended purpose. It is acceptable to cut on a wooden surface. Glass, plastic, iron lead to deformation of the blade and loss of sharpness.
When sharpening a knife, you need to use protective equipment.
If you strictly adhere to the algorithm for working on a sharpening machine, then even a beginner will be able to restore the blade. Using the recommendations received will help you avoid common mistakes in sharpening knives.

How to sharpen scissors - quick and affordable sharpening methods for beginners
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.

The sharpening angle of fabric scissors: what should it be, how to sharpen the tool correctly
0 1 980 views Tailor's scissors
To cut fabrics, special tailor's scissors are used, which differ in sharpening angle and special shape. The device has a massive blade with sharp tips. For proper operation of the tool, proper care and timely sharpening is necessary.
Why scissors don't cut well: reasons
The working condition of tailor's (or tailor's) scissors may deteriorate due to improper use. The blade will become dull when cutting cardboard, paper, plastic and other foreign materials.
Tailor's scissors have a special shape (photo: zat24.com)
Another possible cause is that the screw that holds the blades together has become loose. In this case, it needs to be tightened and lubricated with sewing machine oil. Some models do not have a screw, but instead have a rivet. It is difficult to correct their weakening on your own, so you need to contact a specialist.
What are the sharpening angles on tailor's scissors?
Cutting tools for fabrics are made of durable steel. They have pointed ends, not cut at right angles. This makes it easier to score the edges of the fabric and helps cut even the most capricious fabrics.
The sharpening angles of tailor's scissors depend on the material from which the tool was made. Most often, these are 45°, 60° and 65°.
Additional Information! Sewing scissors differ in appearance. They have massive blades with sharp tips and different sized handle rings (one larger than the other)
At what angle do tailor's scissors sharpen?
Tailor's scissors are sharpened at the angle at which the blades were made. Most often, these accessories have two edges - 45° and 60°. Changing the indicator may damage the instrument.
Preparation
Before sharpening, an external inspection and diagnostics are carried out. To do this, you need to disassemble the tool and separate the parts into separate elements.
Pay attention to:
- blade sharpening angles;
- clamping mechanism (condition of the screw, elastic washers, holes, back surface);
- quality of cutting edge processing;
- smooth running of the blades.
If any parts are worn out or found to be faulty, they are replaced. If necessary, polish the back surface and remove burrs. If the screw is loose, tighten it and lubricate it.
How to sharpen scissors at home
You can put scissors into working condition at home, provided you follow the rules. To do this, use a sharpening machine, a file or a stone with fine grains. You need to be sure that you can maintain the sharpening angle. Otherwise, you need to contact a specialized workshop.
To keep the blades sharp, it is important to maintain the sharpening angle of the tool (photo: sewline.com.ua)
How to sharpen a tool yourself:
- carefully open the scissors;
- take it by the rings so that the ends point up;
- hold a sharpener in the other hand;
- tilt the cutting tool at the desired angle (up to 75°);
- sharply draw a file or a block across the surface of the blade;
- repeat several times.
Recommendations for proper sharpening:
- sharpen towards you, while guiding the tool from the tips to the rings;
- do not move back and forth;
- do not change the sharpening angle of fabric scissors;
- After work, wipe the blade with sandpaper.
Additional Information! It is better to check the sharpness of scissors on thin materials (silk, chiffon). A well-sharpened tool will cut material easily and evenly in any direction.
Special sharpener
You can sharpen the blade using special sharpeners, which are sold in sewing stores. They can also be purchased online from trusted sites by selecting the desired model and delivery address.
Sharpeners are electric, stone wheeled and universal (for example, the Fiskars Universal Scissors Sharpener model). When using a special device, first check the sharpening angle, then firmly take the scissors in your hand and turn on the machine, carefully guiding the blades towards the rings. Don't rush or perform the movements too slowly.
Quick methods using scrap materials
At home, sharpen scissors using an emery stone, moving from the screw to the tip of the tool. Sharpen the entire plane of the edge at the same time, making sure that the angle of the blade does not change. In the process, the resulting burrs are removed.
To quickly sharpen the blades, you should take a diamond needle file or file. It must be remembered that such methods will only improve the condition of the tool, but will not replace a special sharpener.
Important! Tailor's scissors cannot be sharpened with sandpaper, a needle, a metal pin, or other methods that are recommended for office cutting tools.
How to properly use scissors to keep them sharp
The working condition of scissors is maintained with proper care and timely sharpening. The tool is used only for its intended purpose. Do not cut materials other than fabrics.
Proper care will prolong the sharpness of the instrument (photo: crafta.ua)
Rules of application:
- clean after work;
- periodically lubricate the screw, cutters and the point of contact of the blades with oil;
- store in a dry, clean place out of reach of children.
Why does a tailor need to have several sewing scissors?
Each type of fabric requires scissors with different characteristics and sizes, since it is impossible to cut the material and trim the threads with one tool. Leather, suede and draped fabrics are cut with zigzag scissors. They are also suitable for decorative work. For embroidery, a tailor needs a tool with a thin, long blade. To cut the threads, use small, sharp scissors.
Without observing the sharpening angle, it is impossible to restore the ability of scissors to cut well. The indicator must correspond to the value set at the factory. Before sharpening a tool, you need to disassemble it and make sure the parts are in good condition. For more information on sharpening scissors, see the video below.

How to properly sharpen scissors at home, common mistakes
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:
- 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.
- 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.
- 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:
- For cutting soft materials - paper, fabric, it is usually maintained at 60 degrees.
- 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.
Sharpening rules
The method of sharpening them depends on the type of scissors. Most often, housewives use a whetstone. Before the procedure, it is necessary to completely clean the cutting surfaces - take a cotton swab, moisten it in alcohol and wipe the blades.
If there is more serious contamination (for example, paint), chemical solvents must be used. Let's look at various ways to sharpen scissors at home.
If the metal of the product is of poor quality, then constant editing will lead to wear out of the blades - the life of the scissors will decrease.
Grindstone
You can sharpen scissors efficiently on a sharpening machine with abrasive. After turning on the mechanism, the blade is brought to the stone and carefully guided from one end to the other. When one side is completed, continue with the other. According to safety regulations, you cannot work on the machine wearing protective gloves, as they can get wrapped up in the rotating parts.
Some people sharpen scissors on a whetstone, since there is no special apparatus. Its surface is treated with abrasive. The process requires carefulness, but the result is worth it. If the scissors are fastened with a rivet, they are not disassembled. When connecting with a screw, it is better to separate the blades.
Algorithm of actions:
- moisten the whetstone with water and place it on the cloth;
- open the blades of the scissors as much as possible and place them on the block;
- make sure that the plane of the sharpened part is tilted away from you;
- move forward with force, in the opposite direction - easily, without pressure;
- Sharpen the other side in the same way.
It is better to sharpen fabric scissors on a coarse-grained whetstone. In this case, small oblique teeth will appear on the blades, which will help cut the material. It is easiest to hold the tool by the ring-handles, with the tips of the blades pointing upward. It is better to check the quality of sharpening on the fabric.
If the product does not “chew” the material, then the editing was completed successfully. Tailor's scissors can be checked for functionality in the same way. There are fewer requirements for office scissors. As a rule, even slightly dull tools can cut paper.
You cannot change the sharpening angle at which the products were originally sharpened in the factory.
If you need to sharpen the blades of nail scissors, doing it at home is inconvenient. If the edges are almost straight, editing is carried out according to an individual scheme. Nail scissors with round tips are usually not sharpened by yourself, since this operation requires a stone with diamond chips. How to sharpen a tool for cutting metal - it is better to disassemble it, since the halves should be sharpened with a file separately:
- When working with a whetstone, it is not recommended to sharpen the blades to razor thickness.
- After working on a coarse-grained sharpener, you need to “fine-tune” it on a smaller stone.
You should check the functionality of the tool several times. If the blades cut well, there is no need to continue the process.
Position the blade correctly. Slide gently at an angle.
Sandpaper
The method of sharpening with sandpaper is used when it is necessary to quickly restore the sharpness of blades. For this purpose, use paper with a fine grain. Used cloth-based sandpaper is more suitable for final polishing. You can temporarily maintain the sharpness of the scissors by making a long cut on the abrasive paper.
The size of a piece of paper for short-term sharpening is 5x10 cm. After making cuts around the perimeter, the blades will become much sharper.
Foil
Regular household foil will help restore the sharpness of household scissors. This sharpening method is suitable for household and tailor's tools. The process must be performed carefully, as there is a risk of damaging the instrument. Knowing how to properly sharpen scissors will help you always keep the tool in working condition. It is necessary to fold the foil at least six times. Then you should be patient and cut it into strips until the blades of the scissors become sufficiently sharp.
The foil should be thin (food grade)
Gypsy needle
It is possible to sharpen scissors with a gypsy (or bag) needle. The main requirement is a hardened metal needle. The principle of sharpening scissors for iron is used:
- take the tool, open it as much as possible;
- place the needle as close to the center of the fastening as possible;
- we try to press the needle to the top;
- slowly close the blades.
The needle in this case moves towards the ends of the blades. For this method, you can use a regular pin. Thanks to the tips listed above, you can easily learn how to sharpen scissors not only with needles, but also with knitting needles. Everything should be done carefully, otherwise there will be nicks on the scissors. Once the movements are mastered, you can slightly increase the sharpening speed.
Position the needle correctly Press and cut towards the base of the needle
How not to sharpen
The most important condition when sharpening is that you cannot change the factory angle of inclination. All beginners make this mistake. Such manipulation will affect the quality of sharpening and the ability of the tool to continue working. Often they try to sharpen the inner plane of the blade with a file. The effect in this case will be the opposite. File only the cutting edges of the tool.
- For garden shears, sharpening using foil, a needle, or sandpaper will not work. A grinding wheel or whetstone should be used;
- It is not recommended to use a gypsy needle for tailor's scissors. But, in addition to foil and sandpaper, you can use plastic bottles, which are also cut into small pieces;
- Nail scissors and stationery scissors are easily sharpened with a needle, and a sharpening wheel can quickly put them out of use, so it is not suitable.
Another common mistake is when scissors are taken apart. This cannot be done for all types of products; for example, if the blades are connected by a spring or rivet, then they should not be separated. Any inaccurate movement will cause the cutting surface to become distorted. The result of such work is that the tool will be unsuitable for use.
Manicures should not be sharpened with a needle and a whetstone. For gardeners, use only a sharpening wheel. For tailor’s, a needle will not work.
Care of scissors
To ensure the operation of tools, they must be promptly cleaned of dirt. We list the basic rules for care:
- To ensure smooth operation of the blades, after use it is necessary to wipe the scissors with a cloth, preferably without lint. This will help prevent particles of debris from accumulating at the attachment point.
- With frequent use, you need to lubricate the moving parts around the axle with WD-40 type lubricant. After applying the lubricant, you need to lightly work with the blades to penetrate the compound into the joint.
- Vegetable oils should not be used, as they tend to attract dirt particles. The metal of the tool becomes sticky.
- If dirt gets on your scissors, you should wash them with warm water and dishwashing detergent. If the dirt is stubborn, you need to use white spirit. After cleaning, wipe dry with a soft cloth.
- If rusty stains appear (storage conditions have been violated), you need to wipe the scissors with table vinegar. Then polish the metal parts with sandpaper (zero). When processing, do not touch the cutting edge.
The tool must be stored in a dry place. Tailor's tools should only be used to cut fabric. Even ordinary paper and cardboard will damage their surface. The manufacturer guarantees the operation of the scissors without additional adjustments for one and a half years. With constant use, office tools require sharpening approximately once every six months.
If you provide proper care and use, the products can last for many years. You can use the described methods to sharpen scissors at home with your own hands.
If used frequently, lubricate with special oil. Wipe the scissors with a cloth. To remove rust from the scissors, use acetic acid. Dirt can be cleaned with water and dishwashing detergent.

How and with what can you sharpen scissors at home?
During use, scissors lose their sharpness and cut materials much worse. This leads to a deterioration in cutting quality, the edges become uneven, and more force is required. However, many do not know how to properly sharpen scissors at home.
Sharpening scissors at home
How do scissors work and work?
The scissors have a symmetrical design, consisting of two moving parts, which are connected to each other by a bolt or rivet. Each part is a ring connected to a cutting edge. The parts of the structure fit tightly together.
Cutting is carried out due to the presence of a minimum gap between the two blades, which are driven like a lever mechanism. Fingers are threaded through the rings and the lever is activated.
Blade geometry
The blades have the following shapes:
- spicy;
- rounded;
- combined.
Cutting force
Cutting tools are produced for use in various fields. The difference lies not only in the size and geometry of the blades, but also in the amount of cutting force.
The force increases depending on the distance to the axis of rotation: the closer to the axis, the higher.
Sharpening methods
Before sharpening scissors, you need to understand the features of their use. The methods used for knives are not suitable in this case. This is due to the use of the edge cutting method, which requires sharpening angles of 300 or more.
Smaller edge angles are bad because the blade becomes dull faster and the cutting process is simplified. An important feature of the tool is the need to maintain the factory angle, since the design is adjusted to it.
You can sharpen the blades of the tool using the following methods:
- On a special machine. High quality processing, productivity.
- On the grindstone. The method is painstaking and difficult to implement due to the low accuracy of the sharpening angle.
- Sharpening stone. Simplicity and accessibility of the method. Turning is only possible on a perfectly flat surface, angle control is difficult, and grinding speed is low.
To quickly sharpen scissors, you can use the following tools and methods:
- foil;
- bottle;
- with a pin;
- by sharpening with a needle.
Tool
To sharpen scissors, use the following tool:
- sandpaper;
- file;
- machine with diamond wheel;
- whetstone;
- special sharpener;
- homemade gear device.
At home, you may not have special tools, so you can sharpen manicure or sewing scissors using improvised materials:
- a sheet of foil;
- needle, bottle or pin.
How to sharpen scissors at home
To quickly sharpen the cutting edges of a tool with your own hands, you can use one of the following methods:
- Cutting sandpaper sheets with a roughness of 150–200 into 15–20 strips. The method is simple to implement and allows you to sharpen blades evenly while simultaneously cleaning the entire cutting part.
- Cutting a foil sheet (aluminum) 200–250 mm long, folded in 2–3 layers. The sharpening effect increases with increasing sheet thickness.
- Cutting glass jars or bottles, which uses necks with a minimum glass thickness and the same wall thickness. The method allows you to maintain the sharpening angles of the scissors under the condition of uniform pressure.
- Cutting a pin or needle. The method is similar to the previous one in terms of implementation technology.
Sharpening scissors at home
How to sharpen regular scissors?
You can sharpen scissors using a regular whetstone as follows:
- Wrap the stone in a cloth and wet it with water.
- Unscrew the bolt by disassembling the tool. If there is a rivet, you will need to spread the blades to their maximum width for ease of sharpening.
- Secure the tool to the work surface so that it is stationary. It is required to maintain the sharpening angle that was made in the factory during its production.
- The blade is sharpened on the rough side of the stone so that the blades move in a single plane and exclusively in a single chosen direction.
- Point 4 is repeated, but on the side of the stone for fine turning.
- Steps 4 and 5 are performed for the second cutting edge.
- Assembly is carried out: the screw is tightened and the cutting quality is checked.
Before assembly, after sharpening, it is recommended to lubricate the blades with a special lubricant or treat them with an anti-corrosion agent. This will prevent the blade from rusting and maximize its service life.
You can also sharpen with a file:
- The product is disassembled into two parts by unscrewing the mounting bolt or screw.
- One half is secured in a vice so that the part to be sharpened is on top and the edge is parallel to the plane of the fasteners.
- Using a file in one direction, the blade is sharpened. Movements should be slow, with equal effort. If there are defects, turning is performed until they are eliminated.
- The second part of the tool is sharpened in a similar way.
- Assembly in progress.
- The quality of sharpening is checked and, if necessary, all steps are repeated.
How to sharpen nail scissors at home?
Sharpening manicure tools yourself is quite difficult, so in most cases it is easier to purchase new ones. This is due to the use of durable materials (hardened steel or diamond coatings), which are difficult to sharpen by hand. The bending of the canvas is important and requires special attention to maintain a tight fit.
The easiest way is to sharpen with foil:
- The foil is folded several times.
- Use a tool to cut the foil into strips. The more strips are cut, the sharper the sharpness.
- Remaining foil should be removed with a soft cloth.
- The cutting quality is checked, and if necessary, steps 1–3 are repeated until the desired effect is achieved.
A table of typical blade sharpening angles will help you determine the optimal cutting edge angle. The choice depends on the degree of wear and the base material of the tool.
The quality of blade sharpening can be checked by cutting thick fabric. Synthetic materials are suitable for this.
The needle sharpening method is also suitable:
- A thin long needle made of durable steel is selected.
- The tool opens so that a needle can be inserted near the axis of fastening of the parts.
- The needle is inserted between two blades, and the process of simulating its cutting is performed.
- The needle moves further, similar steps to step 4 are performed.
- The action is performed several times until the desired level of sharpening is achieved.
How to sharpen garden shears?
Sharpening scissors for gardening needs is done as follows:
- take a sharpening machine;
- a grinding wheel with a diameter of up to 35 mm is installed;
- a guide is attached to the machine, which is set at the desired angle;
- the power of the machine is turned on;
- along the guides, the edge of one blade is sharpened alternately, and then the other.
If after sharpening there are small nicks left on the edge, then there is no need to remove them, as they can be used for cutting dense materials. No finishing is required after sharpening.
To improve sharpening accuracy and increase productivity, it is recommended to make a special fixture for fixing.
How to sharpen sewing scissors?
If tailor's scissors become worse at cutting fabrics, then they need to be sharpened. To do this, it is not recommended to use improvised tools, since the use of a special machine is required.
Sharpening tailor's scissors can only be done if the position of the edges is accurately fixed relative to the abrasive part of the tools. It is permissible to use machines with blade clamps, special devices and sharpening discs or files.
The main difficulty is the high requirements for sharpening angle accuracy, which affect the cutting quality.
To check whether the sharpening was carried out correctly, it is enough to cut the thin fabric along the entire length of the blade. If fabrics wrinkle or tear when cutting, then it is necessary to understand the cause and eliminate it. How I sharpen scissors (How to sharpen scissors) How to sharpen scissors correctly

How to sharpen scissors at home
Manicure, kitchen, office scissors - you can’t do without them either at home or in the professional sphere. If the tools become dull during use, there is no need to rush to get rid of them. Knowing how to sharpen scissors, it is easy to return them to functionality. For sharpening, you can use special professional tools or use the “grandmother’s method.”
Professional sharpening of scissors
For self-sharpening, only those scissors that are used in everyday life are recommended. It is better to entrust the sharpening of manicure tongs, thinning scissors, and tailor's scissors to a professional craftsman. They use a special electrical device that has attachments for a specific type of scissors or forceps.
You will have to spend money to pay for the work of the master, but professional tools are expensive, so you cannot make mistakes when sharpening. If scissors are used only for household purposes, then you can get by with simple sharpening methods used by many housewives in everyday life.
At home, you can sharpen scissors with your own hands if you have 3 devices:
- Diamond circle. It can sharpen any tools, even scissors and nail clippers, but the unit copes especially well with large sharp objects. For example, pruning shears, animal shears, and gardening tools are ideal for sharpening on a wheel. If you need to sharpen hairdressing scissors or tweezers to remove hair, it is better to use a rounded stone or a diamond file.
- Sharpening stone. The main difficulty when working arises in the choice of grained timber. If sharpness is required, then the work is done with the fine-grained side, and in all other cases - with the coarse-grained side. Scissors used for cutting hair need to be sharpened only with the coarse-grained side, otherwise they will turn out to be too sharp and will no longer cut hair. The strands will simply slide along the tip of the tool.
- File. With the help of this unit you can solve a lot of problems, for example, such as sharpening scissors at home. A file can be used to sharpen metal scissors with teeth. The main difficulty lies in selecting the size of the tool.
If scissors are often used in everyday life, then it is better to purchase a special device that will adjust their sharpness. In a household goods store you can purchase a special universal sharpener for knives and scissors; it will be a “godsend” for many housewives.
Rules for working at home
Regardless of what tool is used, you need to know how to sharpen metal scissors at home correctly in order to get a good result. It is important to know 4 rules:
- It is necessary to take into account the factory sharpening angle. Self-sharpening of manicure or other scissors is carried out only at the established angle. If you break the rule, you can permanently damage the tool for manicure and cuticle trimming.
- The tool sharpens towards itself. Movements must be constantly controlled; you cannot sharpen the side cutter using back and forth movements. Tools can be sharpened from the nose to the rings.
- Fighting burrs. If there are burrs after sharpening, they are removed with a fine-grained abrasive. The only exception is hairdressing equipment; it cannot be made too sharp.
- Checking the work. It is made according to the material for which the tool is intended. For example, if tailor scissors have been sharpened, they need to be checked on the fabric. A thin piece of fabric is taken, hung and cut. If the cut is smooth and pieces of fabric are not caught, it means the job was done correctly.

Scissors, along with a knife, share the palm among cutting devices used in the household. But, unlike the main kitchen assistant, their scope of application is not limited to this territory.
As you know, scissors are indispensable for working in gardens, tailor shops, and hairdressers. The purpose of the instrument determines its shape and size. Janome sewing machines are used in the sewing, knitting, footwear and other light industries, as well as in everyday life.
You can purchase it at the Lapka specialized sewing equipment store.
- How to properly sharpen scissors at home: preparation
- How can you sharpen scissors at home?
- Checking the sharpness of the cutting tool
During operation, all scissors tend to become dull and can no longer cut as well as at first. In this case, the idea arises of purchasing new ones, because their price is affordable for everyone, but knowing how to sharpen scissors at home, you can extend their service life .
How to properly sharpen scissors at home: preparation
Drawing a parallel with skates, the blades of scissors should have a similar sharpness. The main principle is that uniformity and linearity must be strictly observed during processing. The angle for sharpening is selected taking into account the hardness of the material from which the cutting device is made. The lower the indicator of this mechanical characteristic, the smaller the angle should be.
If the scissors cannot cope even with cutting ordinary paper or thin fabric, it is necessary to diagnose the cutting edge and other elements of the tool:
- Checking the hinge assembly . Weak fastening of the cutting edges practically negates the correct functioning of the tool. If the scissors are screw-type, then the threaded connection should be tightened. If they are riveted, they crimp the rivet. In scissors connected in the classical way, you need to check for play from time to time.
- Geometry assessment . Looking at the blades from top to bottom, on working scissors you can observe a negative bend angle. There should be close contact at the point where the cutting edges meet. Separated blades, even with a slight play between them, will never fully cut the material, even if their edges are perfectly sharp. If you need to bend the blades a little, you can do this yourself, observing safety precautions.
- Checking the condition of the cutting edges . Before you start sharpening the scissors, you need to carefully inspect them. There may be nicks or rust on the metal frame. It often happens that perfectly sharpened blades begin to cut poorly due to some small chip that does not ensure complete mating of the edges. It is enough to eliminate it, and the scissors will be suitable for cutting.
- Cleaning the surface of cutting edges . You often have to use office scissors to cut adhesive tape. The adhesive sticks to the sharp halves, followed by particles of dust and dirt. The remaining pieces of tape block the cutting edges and stick to the material being processed. You can use alcohol or solvent to remove foreign objects and glue.
How can you sharpen scissors at home?
- File. You can sharpen scissors or a kitchen knife by turning to tools such as a file, diamond file or whetstone for help. To sharpen the blades, you need to drag it several times with force along a special block located on the table. With one hand you need to press it to a flat surface, and with the other you need to sharpen the edges, moving from the rings to the ends of the scissors. A slightly different scheme is used to work with a file.
The file handle is placed in the working hand, and the spread halves of the scissors are placed in the other hand. For convenience, the sharp end rests on a non-slip plane. After sharpening, use your finger to test how sharp the edges are.
- Sandpaper. Another quick way to sharpen is to use fine-grained or coarse-grained sandpaper. The abrasive sheet is bent in half, leaving the working part outside. Make several cuts.
This method allows you to slightly sharpen dull scissors, but only temporarily. It is problematic to grind down the steel layer using sandpaper, so this technique is only suitable if there is an urgent need to cut something off.
- Aluminium foil. You will need a medium-sized foil sheet, which needs to be folded along its entire length in several layers. Cut the resulting thick strip of foil.
The main thing is that the cut is made across the entire thickness, from the base to the end of the rolled sheet. The efficiency of sharpening the tool depends on the number of thin strips cut. When you only need to sharpen the cutting tool a little, it is enough to cut off a couple of wide strips. At the end, the blades are wiped with cotton napkins to remove stuck particles of foil.
- Sewing needle. An ordinary needle is suitable for sharpening scissors.
Open the scissors to their maximum width and place the needle near the section. The cutting edges slowly close together, thereby moving the needle to the bottom of the blades. The procedure is repeated several times.
- Cup . The problem of dull scissors is solved with a ceramic cup. It is turned upside down and the sharpened edges are moved back and forth.
- Steel wool. A washcloth used for washing dishes also sharpens metal very well.
To restore the sharpness of the blades, you need to cut the washcloth into several parts, making sure that the entire length of the cutting edges is used.
Checking the sharpness of the cutting tool
After sharpening the scissors, you need to evaluate their cutting ability. Exactly the same measures are necessary to check whether the blades need to be sharpened at all. As practice shows, not in all cases the lack of sharpening has a negative effect on the sharpness of the tool.
Sometimes the reason for poor cutting properties lies in severe loosening of the fastening screw . Blades that do not fit well together will crush and chew the material. The solution to the problem is quite simple. You just need to tighten the screw and try to cut something.
A possible problem that you may encounter while cutting is a small gap between the sharp ends. The presence of such space will not allow high-quality cutting of the material. If the cutting edges do not converge at a certain point, the material begins to wrinkle.
Having discovered that the edges diverge, you need to use a file to process a special stop on each cutting blade. They are located next to the rings and are small metal or plastic soldering. Grind them down carefully, periodically checking to ensure that the distance is reduced to the required mark.
It will take endurance, the work is monotonous, but not difficult.
If the manipulations done did not bring results, then sharpening is indispensable. To check its feasibility, take a small piece of fabric . Hang it so that its edges hang freely. Then the incisions are made. A crooked cut indicates that the tool needs to be sharpened.
