For high-quality knives, we must know how to care and maintain. A soldier who does not love weapons is by no means a good soldier.
Care and maintenance of tools should pay attention to the following issues:
First, try to touch the blade with as few hands as possible. First of all, this is for safety. If the angle between the finger and the blade is slightly different, you will be “gloriously injured.” Some foreign-made sabers contain a small amount of chemical components in the blade. Trauma, wounds are still difficult to heal. Secondly, the sweat on the hands has a corrosive effect on the blade. Even if the blade is not rusted, if it is not cleaned in time, it will form unsightly marks on the blade over time, affecting the appearance of the blade;
Second, do n’t use a knife to smash coins and other hard objects. Some people use a knife to cut and hit a stack of coins in order to test whether the knife is sharp. It is illegal to destroy the renminbi first. Second, the use of different types of knives is also illegal. Not the same. Although some knife types are made of high-quality steel, their functional design is mainly for "stabbing" rather than "chopping", especially for folding knives. Repeated unnecessary chopping will damage the normal opening and closing effect. Generally test whether the blade is sharp. You can use an old newspaper to roll it into a solid paper roll with a diameter of about 5 to 7cm. You can tilt the blade about 20 degrees to cut it from top to bottom. You can see if the blade is sharp or not. Any damage
Third, regular cleaning and maintenance. After long-term storage or use of knives, they must be cleaned. Under the principle of safety, the knives and scabbards should be carefully cleaned to remove the dirt on the knives and the sludge on the scabbard. , To check whether there is fine sand in the opening and closing position, and if necessary, remove it in time;
Fourth, oil the tools on a regular basis. The tools are coated with various anti-rust grease when they leave the factory. Generally, they do not need to be wiped off. After careful cleaning, the tools should be coated with a layer of protective oil. A common special protective oil for cutting tools is the "SENTRY" brand special protective oil produced in the United States. After it is applied to the cutting tool, it will produce a layer of protective film for a period of time to prevent the tool from rusting or plaque and has a lubricating effect. In addition, the common WD-40 anti-rust lubricant on the market is also a good choice. Some serrated tools should be carefully coated with rust-proof grease evenly when oiling. There are also some collectors of knives who tightly wrap the knives with lubricant-soaked cotton yarn for protection purposes;
Fifth, unless you are very sure and necessary, don't sharpen the knife easily, even if the knife sheath that comes with the knife is inlaid with a sharpening stone. Tool grinding is a very professional technique. Different tools and different grinding tools have different grinding methods, especially industrial electric grinding wheels. Improper use will cause the tool to be scrapped. It is recommended to use the tool before grinding it for the first time. Knives or scissors in the kitchen of your home are repeatedly practiced for trial grinding several times, and after you find out your experience, you can manually sharpen or sharpen the knife.
