That's very interesting. I've never seen anyone do it that way. When you were working out your process, did you try going the opposite way? Fully harden the blade first, temper to 650 to 750 F, then torch harden the edge? I know a couple makers that take pre-hardened fully hardened blades at about 49 to 51 HRc and torch harden the edge.
