Normalizing (to the best of my mind) is the basically a process in which by heating a piece of work to a non magnetic state, then letting it cool down to (about) room temp. Then repeating this a few times. The idea is that it will help relieve internal stresses built up in the work piece from forging, working etc. There are on here some folks that would probably explain it a bit better than myself. Do a search over in the knife/sword/pointy thing forums and I will bet you you will net some more complete info.
