This one's a question for the steel nerds out there. It seems that although there's a lot of variation in heat treat techniques and results, the differences in performance aren't necessarily captured by the Rockwell C number. Negative examples that come to mind are CRK's "old" heat treat of S35VN, and the "bad" ZT ELMAX that existed for a short while. Positive examples include the HT work of Paul Bos, Paul Farner, and Renzo Fantoni. In an ideal world, is there another standard measure of heat treat results, besides RC, that makers should be putting on their spec sheets?
