How to adjust and sharpen scissors at home

http://prntscr.com/9pwf2i -If the scissors began to cut poorly, this does not mean that they must be replaced with new ones. Having figured out how to sharpen scissors at home, you can give a familiar life a second life and show yourself as zealous owners. Moreover, old tools made of durable steel often surpass modern Chinese crafts in quality.

Preparatory work before sharpening

The easiest way to sharpen home scissors or scissors for haircuts. Accessories from a manicure set (nippers, tweezers and scissors) are much more complicated.

Before you start sharpening the scissors, you must carefully examine them. Perhaps the reason for their poor performance is not only and not so much that the attachment-axis between the knives has weakened. Usually a bolt or rivet is used as an axis on the scissors. If the halves of the scissors are fastened with a bolt, then you can simply tighten it.

If the blades do not close together with the screw tightened, you can slightly sharpen the heel-limiter next to the bolt hole, thereby bringing them closer to each other. Do not try to bend the scissor blades for a better fit. This, most likely, will not correct the situation, but the tool can be damaged forever.

If a rivet is used as a connecting element between the blades, then, if necessary, it can also be pinched. Rivet the scissors only in open form, otherwise they can be ruined. To properly tighten the rivet, the scissors must be opened and laid on the anvil (at home there is always a metal object that can be used for this purpose) and with the help of a beard, gently flatten the rivet, periodically checking how the blades open and close.

If the problem persists, then the scissors are dull and should be sharpened. This can also be done at home.

How to sharpen scissors yourself

Usually a whetstone (whetstone, donkey) is at home and is used for sharpening and straightening knives. If not, then it can be purchased at almost any hardware store. Usually the bars have two different sides - fine-grained and coarse. At the first stage, the rough side of the donkey is used. Sharpening work is carried out in the following order:

Grinding scissors with an emery stone

• The donkey is laid on a cloth and moistened with water.
• If the scissors are fastened with a screw, then they should be disassembled, if on a rivet, then open the blades as much as possible.
• Trying to observe the inclination of the factory sharpening as much as possible (it cannot be changed), the blade is laid on the donkey so that the plane of the blade is inclined from itself. During sharpening, make sure that the chamfer is constantly parallel to the surface of the bar. With a calm movement, the blade slowly leads away from itself and to the side, so that the bar runs uniformly along its entire length, moving from the end to the joint. These steps should be repeated several times until the blade becomes sharp. The blade can be carried out on the bar only one way!
• After sharpening both blades, it is desirable to direct them on the fine-grained side, several times passing along the bar alternately with the flat inner side of the blade and the chamfer.
• Collect the scissors and check how well they cut.

Grindstone

To check the sharpness of sharpening, you need to take a flap of thin tissue and, holding it on weight, cut with scissors. If the cut is even and the material does not bite between the blades, then the tool is perfectly sharpened and ready for use.

Features of sharpening manicure scissors

Unlike haircut tools, it’s difficult to sharpen manicure scissors at home. If the blades of such scissors are straight (usually they are nail scissors or universal), then they can be repaired and sharpened in the same way. But you need to use a small bar with fine grain, preferably with diamond chips. You should carefully consider the inclination of the cutting chamfer - it differs from the angle of inclination on other scissors.

Nail scissors

If cosmetic scissors have thin curved blades (for skin and cuticle), then it is almost impossible to repair and sharpen the house. On their own, with such tools, you can tighten the connecting bolt or slightly adjust the blades with a needle.

How to sharpen manicure tweezers

Manicure masters often divide nail clippers and skin clippers, calling the first clippers, and the second - tweezers. First, we'll figure out how to put the nippers in order at home.

• When sharpening nail clippers, the backlash, which is often present even with completely new tools, should be removed first. If this is not done, then to achieve the correct convergence of the cutting parts is almost impossible.
• A narrow diamond block must sharpen the inside of the blade, aligning the cutting edges.
• Sharpen the blades from the outside, touch up the tips.
• Nippers are laid on the table, clamped and sharpened both blades from the outside at the junction, trying not to disturb the geometry. This operation must be carried out until the mirror plane is barely visible on the edge of the blade.
• The blades are polished with a piece of leather or polishing paste.

Manicure tweezers

If the closure of the cutting surfaces is tight (checked by viewing in the light) and the wire cutters are cut rather than tearing the plastic film, then sharpening is carried out qualitatively.

Tweezers are a little harder to grind. Although the operations are almost the same as with the nippers, they should be carried out very carefully, carefully and slowly. They require a lot of patience, but sharpening makes sense, since good, high-quality tweezers are expensive. The most important thing when sharpening is to achieve complete convergence of the jaws along the entire length. Otherwise, the tweezers will tear the cuticle. A properly sharpened tool removes the skin with light pressure, leaving a smooth cut.
