anvilring...They are clay hardened.....
Jim...Too late.....I don't even bother unplugging or putting away my angle grinder. Use it about every time the shop light gets turned on.
By the way, my wife wants the names and addresses of the varmits that talked me into another hobby.......
Thanks all for the advice/encouragement...
edited::::Forgot to mention - the tanto kitchen knife has a 6-1/2"X 5/32 thick blade (chisle-ground(on one side)). It is ment for chopping vegetables. It sharpens up incredibly sharp and chops like an axe. Hasn't dulled much after the 2X4 test. Still shaves arm hair. However, I probably didn't concentrate the chops on one section of the blade as well as I should for the test to really prove anything. Really like O-1 steel!
