Thread: CPM M4 steel for razors

I'll just roll this out on the floor for everyone to look at: Selecting Hi-Performance Tool Steels

In this end of the cutlery spectrum, take note of the fact that M4 has more vanadium carbides than M2 for the purpose of wear resistance. This should increase the frustration of anyone honing this type of steel because the blade will likely polish the stones unless the grit in the stones is harder than the steel.

I can testify that the High Speed Steels like M2 or M4 or the CPM variations of like kind will make a good enough blade to cut other blades. For cutting hair, I'm sure that it will be a case of over-engineering to get the job done. I enjoyed the experimentation when I did it, I hope you do too, that's what makes building a blade really fun.
