What metal for a profile tool

[Eric CoxParticipant @ericcox50497]

I need to make a half moon (concave) profile tool.

I can't for the life of me remember what material to make it from.

Gauge plate (O-1) hardened and tempered has worked fine for me. JD

Flat ground stock[gauge plate], machine the profile when soft, harden & temper then use.

Well the "classic" way Eric was to anneal an old file, grind or file the teeth off, drill a hole of the right diameter in it, cut off the unwanted half and then harden & temper the remaining bit.

A slight improvement on the idea is to bore the hole with a slight taper, which will provide more clearance for the cutting edge.
