RacerRik you are wrong. Case hardened mild steel(1018) is a good idea. I would go .005 deep to 45 rockwell. Too deep will make it brittle. The case will give you a strong tool with a tiny bit of flex as an assurance against snapping.

I have tested several steels for jobs that required a wear resistant surface along with bending strength. Even 12L14 which on its own is a very weak steel benefits from a shallow case hardening. The key is to not go too deep and too high on the hardness. You can use a tool steel, but due to the thin nature of the tool, hardening throughout can lead to snapping......sorta like a small dia. drillbit
