I've made a few kit knifes, but I don't have much knowledge of steels. I need some help on what type of steel to use to make a tool for a friend. The tool is going to be similar to an awl with a 1/8" round or square shaft that will have a sharpened edge. Sharpness is not a major concern, but the shaft needs to be stiff enough that it won't bend, but still not be brittle. Will this be helped by tempering. Also, I'd prefer an easy to find steel that can worked with a grinder or belt sander
