I'm looking into the posibility of getting a heat treat oven for stainless, instead of sending it off for heat treat. I love Paul Bos's work, but it's a little time consuming to get a batch together and sent to him when I could do three or four blades myself. The stoping point is lack of liquid nitrogen, I know from testing it realy makes a performance differance in stainless and to a lesser degree with carbon steels.
Where could I get a thermos sized amount at a time?
