How to sharpen scissors at home?

Where to start

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

In addition, before you start thinking about how to sharpen scissors at home, check their entire design. This primarily concerns the hinge assembly. This is a small screw that connects both sides of the scissors. Most often, this is exactly the screw, and if it loosened, thereby disrupting the performance of the scissors, tighten it.

There may be a rivet in its place, which may also loosen. In this case, it must be re-squeezed, thereby returning the halves of the scissors to the desired state. In this case, the main thing is not to go too far - if a screw or rivet puts a lot of pressure on the moving parts of the scissors, they will also work poorly.

Modern 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 need to think about loosening this part.

Method 6. Special tool

A special sharpener will allow you to sharpen the blades with minimal time and effort. These devices are available at most hardware stores and are mechanical or electrical. In the process, the blade needs to be moved away from you. The sharpening angle is about 75 degrees. The sharpening disc will do the job quickly and efficiently.

A significant drawback is that experience and a firm hand are needed to work with such a device, otherwise the blade will be damaged.

The professional grinding wheel with an electric drive certainly belongs to the special tool. It is better to entrust the work with it to professionals. An inexperienced grinder runs the risk of not only spoiling the scissors, but also harming his health.

All the methods given in the article will allow you to sharpen the scissors to the desired sharpness. If any method does not work the first time, then you should try again or change the method. Also, don't forget about the bolt that connects the cutting surfaces. If you twist it, then the metal surface will "work" better.

Features of sharpening and working with the tool

Before sharpening the scissors, you need to disassemble them.

Sharpening is not a very difficult process that can be handled quite well at home. For work, you need to use a special sharpening machine, but if it is not there, then a file, a sharpening block with large grain (or other materials) will do. After sharpening, coarse-grained bars leave oblique small teeth on the surface, but this is not dangerous, since it is they that allow you to perfectly cut the material. It is best to use a special electric machine for work. But it takes experience to use it.

Tool dressing procedure:

1. Sharpen the blades only towards you, while the movement will be from the ends to the rings.
2. The angle of the factory sharpening must not be violated under any circumstances. Its value will be in the range of 60-75 °.
3. The process is simple, it begins with the fact that the scissors must be carefully opened, then take them in one hand, and the sharpener in the other. Hold the tool only by the rings and firmly. When doing this, the tips should look up, not down.
4. Next, you should tilt the scissors at an angle convenient for work, but not more than 75 °. After that, you need to sharply drag a bar or file along the surface of the blade from end to axis.Several such movements will be required.

If a special machine is used, then you must first check the sharpening angle, then firmly take the scissors in one hand, turn on the machine. To sharpen the scissors, it is enough to carefully guide the blades to the rings. It is impossible to rush, but also to delay. Regular cold water is used for wetting.

Sharpening with the help of available tools 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 tools at hand. Of course, there are sharpening devices and machines, but they are mainly resorted to when it is necessary to restore the sharpness of the blades on professional scissors.

Smooth metal bar

This is the most affordable way to sharpen your scissors at home. You will need any small diameter steel rod with a smooth surface. This can be a gypsy needle, an awl, a screwdriver, a safety pin, or even a simple paper clip.

Slightly worse, but still possible, use a AA or AAA coin cell battery.

Move the scissors apart so that the rod fits as close to the tie bolt as possible. After that, lightly pressing the handles, begin to bring the blades together, and move the used tool away from you towards the cutting ends. Do this 10-15 times and check how the paper is being cut now. If the result is still unsatisfactory, try 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 bar.

Spread the scissors as far as possible. Place the bevel of the blade at the top against the rim of the cup and, pressing lightly on it, sweep over the abrasive with a pull towards you. The movement during 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 the kitchen for baking food. Take a roll and tear off a piece 20-30 cm long. Fold it 6-8 times along the length to get a dense multi-layer strip. After that, start cutting the foil lengthwise using the entire length of the blades. After 10 cuts, check the sharpness and, if necessary, repeat the steps.

Fine sandpaper can be used instead of foil. It should be folded in half so that the abrasive remains on the outside of both sides. In this case, the number of cuts for the first attempt can be halved. After finishing work, be sure to wipe the blades with a damp cloth to remove any residual abrasive.

Dishwashing sponge

Also present in most apartments and can be used as a scissor sharpening tool. The principle of using a sponge is the same as in the case of foil and sandpaper. However, the size of the metal sponge that you can buy in the store is usually smaller than the length of the blades. Therefore, it should be stretched so that the entire cutting edge of the scissors can be used.

Sharpening with a special tool

In hardware stores, you can find a wide variety of tools and tools for sharpening scissors. If you decide to buy any of them, remember that the principles of operation of knife and scissor blades are very different.

Sharpening stones

An abrasive stone or block is considered the simplest tool for dressing any cutting blade. When sharpening scissors, it should only be in contact with the upper edge, sharpened at a certain angle. When working, you must be extremely careful and try to maintain as accurately as possible this angle of sharpening of the scissors, specified by the tool manufacturer.

The movement of the scissors over a stone or a block along the blade should be done only in one direction with light pressure. Moving back and forth is not allowed. If you unscrew the tie bolt and disassemble the scissors, it will be more convenient to work.

Files

A flat or triangular file with a fine cut is a better tool for sharpening. Editing principles are the same as for stone. The tool moves along the cutting edge and only in one direction. When fastening the scissors in a vice, it is easier and more convenient to work.

The main disadvantage of this method is the likelihood of uneven sharpening. Therefore, try to ensure the same pressure with your hands on the tool throughout the entire time and count the number of movements performed for each blade.

Sharpening machine

Rotating abrasive wheels are installed on special machines for sharpening cutting tools. Processing occurs across the cutting edge at a certain angle and, if you do not have the skills of such work, then it is better to refuse mechanical sharpening so as not to spoil the scissors and not get injured.

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 nail clippers, thinning, tailor's scissors to a professional master. They use a special electrical device with 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 no mistakes can be made when sharpening. If the scissors are used only for domestic 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 tools:

1. Diamond wheel. They 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, garden tools are ideal for sharpening on a wheel. If you need to sharpen hairdressing scissors or hair removal tongs, it is best to use a rounded stone or diamond file.
2. Sharpening bar. The main difficulty during work arises in the choice of a granular bar. If sharpness is needed, then the work is done with a fine-grained side, and in all other cases - with a coarse-grained side. The scissors used for cutting hair should only be sharpened with the coarse-grained side, otherwise they will be too sharp and will stop cutting the hair. The strands will simply slide over the tip of the tool.
3. File. With the help of this unit, you can solve a lot of tasks, for example, such as sharpening scissors at home. A file can be used to sharpen metal scissors with teeth. The main difficulty lies in the selection of the tool size.

If scissors are often used in everyday life, it is better to purchase a special device that will correct their sharpness. In a household goods store, you can buy a special universal sharpener for knives and scissors, it will be a "godsend" for many housewives.

Work at home rules

No matter 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:

1. The factory-cut angle must be taken into account. Self-sharpening of manicure or other scissors is carried out only at the set angle. If you break the rule, you can ruin the manicure and cuticle trimming tool irrevocably.
2. The tool is sharpened on itself. Movements must be constantly monitored, you cannot sharpen the side cutter with forward-backward movements. Tools can be sharpened from the nose to the rings.
3. Deburring.If there are burrs after sharpening, then they are removed with a fine-grained abrasive. The only exception is hairdressing equipment, it cannot be made too sharp.
4. Checking work. It is made according to the material for which the tool is intended. For example, if tailors' scissors were sharpened, then they need to be checked on the fabric. A thin piece of fabric is taken, suspended and incised. If the cut is straight, the pieces of fabric are not caught, then the work is done correctly.

If the design of the scissors allows, then it is better to disassemble them in order to simplify your task of how to sharpen nail clippers at home. The blades are sharpened separately, so it is more comfortable to work and the result is better.

Sharpening angle of kitchen and hunting knives: the importance of care

The sharpening angle of kitchen knives ranges from 30-35 degrees, but for hunting knives it will be necessary to select taking into account the following nuances:

• if you have to sand the prey and make thin cuts, then the sharpening angle should not exceed 15 degrees;
• sharpening of the hunter's universal weapon is carried out according to the parameter of 25 degrees (maximum);
• rough cutting of the carcass of prey is performed with a knife with a sharpening angle of 45 degrees.

Causes of rapid wear

Kitchen knives dull quickly enough for the following reasons:

• cutting boards made of stone, glass, hard plastic are used in the work - such materials round off the cutting edge of the blade;
• bones and tendons of meat often fall under the blade - the high density of these parts negatively affects the cutting ability of the tool;
• the knife is used to peel the scales and cut the bones of the fish;
• sand, the smallest stones, lumps of earth come into contact with the blade - this often happens when working with vegetables and fruits, so they must be thoroughly washed before work;
• violation of the rules for storing knives - they should not come into contact with any hard objects.

Blades that cannot be sharpened

There are knives on the market with blades that cannot be sharpened - ceramic. They have high quality characteristics, do not lose their sharpness even with prolonged use.

Ceramic blades offer the following benefits:

• do not oxidize when interacting with any aggressive environment;
• do not change color;
• do not absorb food odors (even very specific ones).

Such knives are sharpened once every 5-7 years, but it is impossible to do this work at home - a special professional tool and the presence of certain skills are required.

You cannot sharpen self-sharpening blades, the peculiarity of which is the presence of the smallest teeth on the cutting edge.

The design of a hacksaw for wood and why you need a tool

A hacksaw for wood is a highly specialized cutting tool, the main purpose of which is sawing wood materials. Structurally, a hand saw for wood consists of a blade with cutting teeth, as well as a handle. The blade is the working part of the tool, on which teeth are located in the lower part for gnawing and cutting woodworking materials.

There are many different types of hacksaws for wood, but they all have one purpose - this is sawing wood. And not only dry wood materials, but also raw ones, for example, when pruning a garden. In addition to wood, a conventional wood hacksaw is also used for sawing such materials:

• Laminate
• Bars and logs
• Chipboard
• Foam concrete or aerated concrete - when working with a tool with these materials, you need to take into account that the teeth not only quickly become dull, but also wear out. The constant use of tools for cutting aerated concrete and other materials that contain solids contributes to an accelerated reduction in service life. For such materials, hacksaws with hardened teeth are used.
• Shell
• Styrofoam
• Plywood

A hand saw is not suitable for sawing metal, since a specialized tool called a metal hacksaw is used for such tasks. The hand saw for wood is divided into types:

1. Classic
2. Circumferential
3. Luchkovaya
4. Reward
5. With backing

Each type is designed to perform certain actions. For example, the classic model is suitable for many cutting tasks, but it alone cannot cut the material in the miter box. To work with the miter box, award-winning hacksaws are used. Circumferential models are designed for cutting shaped holes in the structure, which becomes possible due to the special design of the canvas (increasing the width from the spout to the handle).

In addition to the types of the tool in question, they also differ in the thickness of the canvases. The thicker the blade, the more reliable the tool, and also the more convenient it is for them to work. Thin canvases in thickness have their pros and cons. The downside is the possibility of breaking the blade when applying excessive force, but their plus is that, due to their small thickness, they easily slide in the thickness of the materials being sawn (especially damp trees). The thickness of the saw blade for wood is taken into account depending on the type of work performed and planned.

A hand saw for wood, unlike electric jigsaws, circular saws and other cutting power tools, can be sharpened. However, there is also a certain nuance here - only models that were not subjected to additional processing - heat treatment - are related to sharpened hacksaws for sawing wood. To put it simply, you cannot sharpen hardened blades on hand files. Heat treatment excludes the possibility of sharpening the teeth, therefore such tools are considered disposable, but they serve for a long time.

It is interesting! It is easy to distinguish a hardened or hardened canvas from an ordinary one - the first option has a dark color. Moreover, usually only the teeth undergo hardening, but the entire blade can also be hardened. Non-hardened ones have a shiny shade, which indicates the possibility of sharpening the blade teeth when they are dull.

The ways

All types of scissors are sharpened in different ways, depending on the scope of their application and the design of the blades, using specialized devices or manually. Each method has its own characteristics, for example, when using a coarse-grained abrasive material, a rough mark remains on the metal of the scissor blades, which makes the cut even better.

The halves of the scissors must adhere to one another so that there is practically no gap, otherwise they will cut unevenly and poorly

If there is a play in the blades, it is necessary to bring them together with caution, and if the half-scissors are loosened, no great effort is required when squeezing. In the absence of special equipment, they use improvised means (an ordinary bar, a file, even sewing needles and food foil are used)

File and vise

If the use of a vise and a file is available for sharpening the scissors that are used to cut metal sheets, then the following sequence of actions must be followed:

1. the tool is disassembled into its component parts;
2. one half of the tool is clamped in a vice so that the side from which the work is planned is on top;
3. the working stroke of the file should be slow and exclusively "away from you";
4. to sharpen the second half of the scissors, the steps are repeated.

Machine

Using an electric sharpening machine, you can sharpen any blade with a minimum error. Approximate sequence of actions:

1. the guide is set to the required angle;
2. the circle rotates towards the edge of the scissors;
3. practice shows that it is not necessary to carry the edge of the blade over it more than three times so that it is sufficiently sharpened;
4. as an improvement to the circle, you can purchase or independently install a device that fixes the scissors so that sharpening occurs in compliance with a certain sharpening angle, which will increase productivity;
5. this sharpening method does not require additional dressing of the blades.

Grindstone

Sharpening stones have two sides - one coarse, the other fine-grained. As a rule, start sharpening from the rough side.

When working with whetstones, the following sequence of operations is used:

1. it is necessary to wet the surface of the grindstone;
2. sharpening of the tool (working stroke) on the coarse-grained side of the grindstone should occur exclusively with movements "towards you", starting from the tip of the scissors to the ring, always with the same angle at which the blades of the scissors were sharpened during their manufacture;
3. all movements "towards oneself" are performed with the application of force, and during reverse movements, there should be no pressure;
4. then sharpening is repeated in the same way, using the reverse, fine-grained side of the stone;
5. Finally, it can be helpful to use fine sandpaper to remove small burrs.

Sandpaper

If you have a small piece of sandpaper, you just need to fold it in several layers, rubbing side up. Under these conditions, you will need to cut the sandpaper into approximately twelve strips. After the paper has been cut, the remaining sandpaper crumbs can be removed with a damp towel.

Needle

Another peculiar way of sharpening is the point of scissors with a needle. Here is the sequence of actions when using such a rather unusual sharpener:

1. the needle must be hard, scissors should not bite it (for this, the blades are opened, the needle is placed as close as possible to the connection of the halves of the scissors, and they try to cut it);
2. a strong needle will not be able to bite, and as a result of pressing it moves from the hinge to the sharp end of the scissors;
3. for factory-sharpened scissors, repeated repetition of such actions will give a good sharpness of the blades.

An additional method for sharpening scissors at home is cutting aluminum foil. To do this, the food foil is folded and cut into small pieces. For this purpose, fine-grained sandpaper can also be used. The "bottle method" can also be called relatively unusual. There is probably a glass bottle at home that you can try to cut off the throat with scissors. This will also give the blades a sharp edge.

Preparation

Before sharpening manicure tools, preparatory work is required:

Check for backlash. If there is one, then you need to remove it: tighten the bolt that holds the 2 halves of the scissors

It is important that the blades fit snugly together. Sometimes a loosening of the backlash is required to sharpen the blade

There should be a small gap in the connection area. It is necessary to remove dirt with a smooth cloth treated with an antibacterial agent. The tool must be wiped clean. It is necessary to check if there are any defects. With a weak attachment, it is twisted with pliers. The screw should be tightened with a screwdriver. This must be done carefully to protect against damage to the mechanism. If the blades are riveted, a small hammer is used. In the presence of chipping, creases, stains, rust, it is advisable to take the scissors to the workshop, where the defects will be eliminated. Do not boil the tool before sharpening, as this quickly rusts and breaks down. Antiseptic agents are used for disinfection.

After preparing for manual sharpening, the nail scissors are ready. However, there are several effective and safe ways to handle fixtures.
