He might use a heat treating furnace, have a Rockwell tester, and a commercial Cyro quenching set up, and do it right, or send his blades to a commercial heat treater. I don't know, but I would find out before I spent the money on a knife.
That is the reason I send my blades to Paul Bos. A proper heat treating set up is very expensive, and some of the super steels have to be heated in a controled atmosphere or vacuum furnace.
