I would do all the cutting and shaping the A2 while it’s still annealed. Then send off for heat treat with the blade. Does A2 change in dimension any once hardened? That would be my main concern as the fit and finish will be mostly done before heat treat.
Good point. I thought about that, but wondered if hardening it would help it to resist mars and scratches more.
Hahaha....I would also add that sanding and polishing hardened A2 is not fun.
