M4 type steel? Cut stainless and even 17-4PH hard steels.

S series steels can be made quite hard, S5 will quench out at 64-65, S7 what I made hammer parts from doesn't HT that hard, but makes great hammer dies for press forming. I do not know of a knife supply that carries S5 anymore. Metal suppliers yes, but they do not like selling small amounts, S5 would make some awesome choppers like axes and swords.

Does anyone know if it forges well?
Those blades would have been M-2 I think. I've run across them before.
