AISI W107 Knife Steel
Composition Analysis Graph, Equivalents And Overview

W107(AISI) - W107, it's a strict spec alloy from AISI W1 steel family. Popular with custom makers. I haven't seen W107 specifically stated as a blade material, but the fact is W107 is quite similar with W1 with minor differences in alloying materials, and those are on the positive side at that(more of alloying elements). Decent edge holding and ok toughness when heat treated properly. Can be used in various types of knives, from small folders to large fixed blades. Better performance with polished, thin edges if the knife design allows that.
