Hi everyone, I'm after some of your wisdom if you don't mind sharing it with me. I've got an old german Castle and Crown razor with a lovely big etch in it and want to restore it. The problem is if I was to lay it on a hone lengthways the middle wouldn't touch the hone, it would sit about nearly a 1/16" proud of the surface.

I'm not scared to put a bit of work in, problem is the only thing I can think of would be to anneal it and clamp it flat while hot and let it cool. I'd then have to heat treat it again and hope it doesn't warp when quenched and if it doesn't temper it. Any thoughts on this? I have no issues doing the above if you think it would work, but I've never done this with steel so thin. Do you view this as a complete waste of time or worth the challenge?
