'03A3 Heat treat ??

[Any Cal.]

I would give it a shot, myself. If nothing else, have the hardness tested by a machine shop, see how soft it got. It could conceivably be close to proper hardness, and would be fine. If it hasn't slumped or warped due to heat, it seems fairly salvageable. Biggest concern would be that it may warp in the heat treat, which would waste the effort. Maybe find a knifemaker locally with a salt pot heat treat set-up, they may find it an interesting project.

Send it to a commercial heat treater that does actions. I think Blanchards in SLC (http://www.bmproc.com/) may still be doing this. Such a shop can test it before and after HT and will back up their work if they agree to do it. You want the assurance that someone who specializes in that type of work and insures their work thinks it will be safe for use after HT.
