FARMER PHIL is right. have fun with your spikes, then go to used or new spring steel(5160) making several blades and getting the feel of it(5160 is a great steel to practice with, it is real forgiving---52100 is a lot tougher to get right) and the advice here for your heat-treating. Everyone will be glad to assit.
On carbon steel--I hardly ever go over 350 to 400 degrees on the tempering.
Have fun and keep mashing.
