A quick question on normalizing. Do you normalize even when doing stock removal blades, or is it just for forging? If so, how many times would you normalize a blade made from a file? I have 2 knives now made from old USA files and a third file i am working now. The Nichols files will not get soft enough to work. The one i am working now, i brought up to temp slowly in my little forge, working it for about 45 minutes, then left it on my wood stove over night to cool. The outsideis soft, but i still have trouble working it.
