The blade of the paper cutter directly affects the work efficiency, so once the blade is paused, it will have a great impact on the work, so we need to analyze the blade life and what factors are related.
        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. Finally, 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.

        The above are the main factors affecting the blade of the paper cutter. I hope everyone can learn from it.
