[I would have posted this in the quenching media thread, but I can't figure out how to respond to messages in this group. Sorry.]A Korean swordsmith, when asked if he used salt water to quench his blades, scoffed at the idea, saying that the salt would corrode the steel. Is he simply wrong? Salt certainly is corrosive. If he is right, is brine used because the corrosion is minor or only a factor in the long run, because there are ways of counter-acting or elminating the corrosion, because other people ignore the corrosion problem, or what?
