High-speed steel was originally developed as a steel material for knives used in metal processing.
It is a hard steel that does not reheat even at high temperatures, but has a coarse structure.
Powdered high-speed steel is a high-speed steel manufactured by the powder metallurgy method (putting metal powder into a "mold", compressing and solidifying it, and "sintering" it at high temperatures to create high-precision parts, etc.), and the manufacturing process seems to be different from the ground up.
Original high-speed steel was not suitable for kitchen knives, but the metal structure has become dense, and powdered high-speed steel, which is strong and excellent, is popular as a steel material for kitchen knives with excellent hardness and wear resistance.
However, because of its hardness, it takes time to sharpen the blade.
