I rarely disagree with Ray so I don't think that I'll do it this time. You are to be commended with your success at your first try, especially with something like 80CrV2. Not an especially shallow hardening steel. If you can do that well with that alloy you should really make it pop with something like 1075. The real question here, as Ray eluded to, is why do it. What advantage does it give you to have a pearletic spine and a martensetic edge with a dark etched line between? I don't think that there is any purpose in a knife blade, except that it looks neat, unless one is trying to pass the ABS performance test which would probably be better done with differential quenching. No etching necessary.

And, yes, I tried a hamon a couple of times with 9260.
