Alright, so here it is. I have a friend who at one time had a medical grade titanium rod placed into his femur. He is telling me this rod is about 13-14" long and hollow, with a total diameter of about a quarter of an inch. He would like this rod made into some type of blade. It doesn't seem like there is much there to work with, but that's why I'm asking you guys. I know titanium is very hard and probably not the easiest to work with. What are your thoughts? Could this be done?
