And get a strong magnet. You can best identify the correct temperature by checking with the magnet. As soon as the blade is no longer attracted to the magnet, that's when you quench.
I knew you were supposed to heat it up until the magnetism went away. This is the first time I've read that this is dull red, not orange.

Do you quench in oil or water? If in oil, what kind?
