one,howGrinding ToolLet itKeep the blade sharp

If the Tool is used frequently, polishing is also a good maintenance method in order to maintain the sharpness of the blade.But the polishing here is not really profitable, but to correct and clean up the blade edge of the Tool.After being polished, the Tool can be corrected and can remove some subtle scratches.

Use grinding steel

The use of polishing steel is a good method of maintaining tools, especially for frequent use of kitchen knives such as kitchen knives.Frequent use can keep the blade sharp.

One of the most basic polishing steel is a metal rod with a straight groove on it.And better grinding steel after magnetization, the molecules that can attract the tools to re -arranges it into a straight line.After the knife and polishing steel friction, you can get correction and remove some fine scratches.Unbound ceramic polishing steel also has this effect.Diamond polishing steel is also popular as a new trend in the kitchenware industry. Its surface is covered with a layer of single crystal diamond. It has the same good effect as traditional polishing steel, but it is more durable, lighter, and polished than traditional polishing steel.The speed is faster.

When using polishing steel, use the blade to use the blade20The angle is exposed to the top of the polishing steel, and then gently draws the entire blade along the entire grinding steel to the bottom, as if cutting a piece of polishing steel with a knife.Each time the positive and anti -alternation is used, the two sides of the blade can be polished evenly.

A simple way can determine whether it has been polished:Use your thumb to touch the two sides of the blade, if the feeling of both sides is the same, it means that you have been polished.If a side is slightly rough than the other side, then gently polish this side, and every time it is compared, until it feels on both sides.

But it should be noted here that the polishing of tools is a very professional technology. Different tools and grinders have different methods of polishing. If it is not used properly, it may cause the entire knife to be scrapped.Passionate and necessary, don't easily polish the tools.

2. How to prevent knives rust?

The biggest enemy of the knife is rust, and even stainless steel knife cannot guarantee that it will never rust.As long as the conditions are appropriate, rust spots will appear on the stainless steel surface without hesitation.

1, Avoid humid environment and contact with corrosive items

The seaside, south, kitchen, etc., the knife is put on hold in such a large humidity environment for a long time, and it is easy to rust.

In addition, acidic fruit juice, sweat on hand, oil stains, etc. are easy to corrode the knife body, so it is recommended to avoid contact with such items.

2, After finishing the Tool, be sure to scrub and clean it in time

After the Tool is used, clean it with flowing water, then wipe it clean with dry cotton cloth and towels, and place it in a ventilated and dry place.This can greatly reduce the probability of rust.

3Gentle grinding

The best way to take care of the Damascus knife is to regularly polish the tools for gently, and generally wipe it with a clean cotton cloth or towel.

4, Regularly give the knife oil

When the knife is cleaned or not used for a long time, it should be applied to a layer of protective oil.Because after applying a knife oil, a protective film will be produced for a period of time, which can not only prevent the corrosion of the Tool, but also have a lubrication effect.

Specific method:

Put the knife on the towel, apply the knife oil on the body, and then use the cotton cloth to wipe it slightly back and forth on the blade surface to make it slightly heat.At the same time, you can also rub the handle and Tool accessories.

5How to store tools

The Tool is suitable for places where normal temperature, ventilation, drying, and not direct sun. If there is professional temperature control and dehumidification storage cabinet.

Each Damascus steel knife in the artificial workshop is equipped with a special custom leather handmade scabbard. This very flexible leather component has been specially treated and has a certain moisture resistance.It can also ensure that the tools will not wear during the pumping process.It is recommended not to put Damascus steel knife in ordinary leather sheaths that are not treated, because ordinary Skin sheaths can easily absorb the moisture in the air and bring a bad impact on the Tool.

How long does it take to maintain the Tool?

The first thing to remember is that after the knife is used, it should be cleaned and maintained immediately.

Then, if it is played everyday, the new knife is maintained every three days, and it should not exceed seven days as much as possible.After a long time, it can be maintained once a few months. Frequent play, a layer of carbon -like protective layer is formed on the blade surface, bright and aura.

I hope that these maintenance skills will keep your swords a sharp and good state of use.
