Add surfur powder to threading fluid and it will cut it
That's a good tip. I'll remember it. Those two were the scrap knives I hammered from cut off steel. Not super worried about them. Might do a hidden tang handle with no pins. Not sure.
I can't believe the handles hardened so much even though they never came close to the oil. Live and learn.
Tomorrow I'm going to try to harden and temper the full sized 80CRV2 knives I've got ground. Then handles. Then testing.
