I envy quite a few custom blades on here that are made by members on this site.
I'm also pretty interested in the laser etching blades. I cleaned up a vintage blade I want to give to my brother and I have access to a $30,000 laser etching machine we use to label tools/parts for aircraft in the military.

If anyone has more info on this let me know! Perhaps the steel might not heat up enough around the edge of the blade to cause issues to the steel used for shaving. If that's the case then any design wanted on the spine/tang/top portion of the blade that got over-heated and had damage done to the temper wouldn't really matter, right?
