Follow up to some previous inquiries I made recently and more
questions.

The tool is a 3/4 x 1/8 x 2" long piece of W-1 water hardening tool
steel. It's bevelled along one of the long sides like a short planer
knife and it must be razor sharp.

For thin pieces being heat treated they made flat tongs that
sandwiched the metal and held it flat so it didn't curl or skelter.
You could probaly bolt it between a couple pieces of scrap and heat
treat the entire assembly.
Faster stock removal with the blue norzon belts and you can help carry
some of the heat off with bar soap or spray lube like WD 40

Drawing temper in molten solder might be a usefull trick for you to
try.
50/50 is liquid at 417°F and radio solder at 361° F

What is the tool intended to do?
