Need to add pin holes after hardening... help!
I'm making a knife for my father for Christmas, shaped a blade from 440C and hardened & tempered it. Brought it from 21.4hrc to 58.7hrc. And then realized today that I'm not going to get holes in it with my TiN coated bits...
Any suggestions?
I've looked at carbide tipped drills, but would likely have to order them in and that might take too long. I have a TIG welder and considered heating the area I want to drill, but that will ultimately heat the whole knife as well.
Here's a picture in case it helps at all.
