Josh,
Thanks for for the walk-thru on the hardening and tempering processes.

Now all I have to do is get grandpa's cast iron forge with hand cranked fan going and it's martensite city.

Long ago when I fancied myself as boy blacksmith I did use that forge when it was still on the farm to make a new burner grate for grandma's stove. No heat treating, grinding, or honing necessary, thank heavens.
