There are many factors that affect the service life of the blade, but many people don't know that three of them are the most influential. Below I will explain it for you.
         First, the material of the blade must pass the level. The knife is made of high-temperature insert welding of the blade and the body. The blade is made of high-hardness chromium-tungsten-manganese steel and the blade is made of low-carbon steel. The durability of the tool is directly proportional to the hardness of the blade. Secondly, the quality of the sharpening knife, the higher the quality of the sharpening knife, the longer the service life of the cutter, and the better the cutting quality. The last point is to cut the type of material. Whether the blade of the paper cutter is blunt is directly related to the abrasion resistance of the material being cut. When cutting the paper, the speed at which the blade becomes blunt is related to the soft and hard texture of the paper and the amount of ash content.
