I'm gearing up to start making my own razors and I'm looking at my options for tang stamps.

My current plan is to just go with stock removal. I'll (hopefully) have access to a waterjet to cut blanks, and I intend to do all my shaping with grinding tools.

But it looks like to get the kind of stamps I'd like I'll need to go with hot stamps.

To start with, I'll be sending the blades out for heat-treat.

Is it reasonable to think that I could heat the tang with a propane torch enough to get a nice hot stamp before it goes off for heat treating, or would I cause problems down the line with getting a good temper by not evenly heating the piece?
