Hello fellows and lady friends. I am trying to heat treat a tomahawk i made from a old ballpeen hammer. I have annealed, i have tried everything but i cant get this thing to harden. I got to non-magnetic, quenched in canola oil at 140°. That didnt work, then tried water, still not hard, any suggestions?? A file will still bite and now i dont know what to do??? HELP!!!! This thing turned out beautiful but not worth a xxxxx if i cant get it hard????
