I recently purchased a razor from flea-bay, and it's got a blown temper.... I can flex the toe easily with just pressure from my thumb. Since the blade is all but trash and cost me less than $15, it got me thinking that it could be a candidate for me to give heat treating another try in my backyard coal forge. So.... that brings me back to the question posed in the thread title, can a razor with a blown temper be re-hardened? Would it need to be completely annealed first, or could I just take it back to a dull red glow, quench, and them temper at something around 230 degrees Fahrenheit? I realize that the whole thing could warp once heated, but once again, it's already screwed up.
