I have a customer wanting an 18th c. hunting sword. 17" blade, by 1 1/2", 1/4" thick. Would 01 be a suitable steel, and if so, What would be a good temper range for strength. On a recent thread, Kevin mentioned a condition that lowers impact strength when 01 is tempered much beyond 450o, and up to 600o. If tempered around 600o / 650o, what could I expect as far as impact strength, and flexability? I believe there would be adequate hardness for the edge, considering it is a sword, am I right? Or should I just go with 5160? this will be stock removal.
