Finally got the knife to harden. Well, all but a small section very near the handle. I am really not sure on how bad that really is. The outer tip is for chopping and will take the most abuse, and hardened very well. The inner, its to be used as a draw knife section and scraper. Being that it will be the most lightly used portion, hopefully its edge will last. I really hope the differentially hardened knife wont fail because of this. Also, there is a slight bend in the blade from the forge. Without sticking it back in there, I am not sure how to correct this. Its not bad, you have to sight down the spine to see it, but it is there, and I am running out of time.
