RJ Martin does a great job supplying this forum with heat-treating expertise and fielding complicated questions. The KnifeNetwork class does not replace this forum. It is a basic course for beginners and intermediate makers who want to learn HT from hands-on instruction, beginning to end.
I'm going to take the course too, and I expect it will give me a more solid understanding of the fundamentals that I only think I know.
Plus - they told me that if I'm taught to point my blade to Magnetic North during the quench, I'll get a full refund.
