The stress placed on an axe is different than the stress exerted on a knife and so I am not sure that the best knife steel automatically equates to being the best axe steel. Do any of you axe makers out there have a favorite steel that you like? If it helps to know, I would plan to use the axe in soft woods like pine, willow, alder, maybe tamarak. The axe would be used to feel trees as well as split wood. Also, the axe would probably see use in very cold temperature too, I don't know if that makes hardness a problem or not.
