Which utility knife is the sharpest? In fact, this is a contradictory question, because the sharpness of the utility knife often depends on the sharpness of the blade.
So there is no brand of utility knife that is the sharpest.
In this way, it can be seen that choosing a good utility knife is to choose a good utility blade, and it depends on the material of the blade.
The material of the utility blade: carbon tool steel, high carbon steel, alloy steel, etc., which of these materials is the best?
1. Carbon tool steel. Carbon tool steel has high hardness and can maintain high hardness and red hardness at high temperature, as well as high wear resistance and appropriate toughness.
2. High carbon steel. After proper heat treatment or cold drawing hardening, high carbon steel has high strength and hardness, high elastic limit and fatigue limit, and acceptable cutting performance, but poor welding performance and cold plastic deformation ability.
3. Special alloy steel. The blade made of special alloy steel has the advantages of being sharp and rust-proof, tough and not easy to break, finer grains, and easy to grind.
