I thinking of building a small fixed blade for myself, nothing too fancy. I was wondering if anyone knew of some common flat steel that would make a good knife blade. I can't forge it and I have limited power tools so it will mostly be done by hand with a small hand grinder or file. I've ground blades out of old files before when I was a kid. In fact I think I still have one somewhere that I made. I'm trying to think of what would work good. For instance a friend of mine made a machete out of an old chainsaw bar. Thanks for any help.
