So I have been seeing a number of the "high speed, low drag" type tactical knives for years that are made from stainless super steels like S30V, S35VN, Elmax, etc. The maker/manufacturer picks a very expensive PM stainless steel and then puts a coating on it. Why? Why not pick something that is tougher but has good abrasion resitance like say CPM 4V/Vanadis 4E, CPM M4, CPM 3V, ZWear, etc? Why would you give up the extra toughness in a hard use blade for corrosion resistance if you are going to coat the blade with a corrosion resistant substance? Just being that contrary old get off my lawn guy.
