· My choice to change our folding knife blade steel to S30V was thoroughly thought through, as was the selection of RC hardness 58-59. I was privileged to be involved in the development of S30V with the metallurgists at Crucible Steel – they asked what attributes I wanted in a steel and they delivered. At RC 58-59, the blade will hold a good edge and will be easy enough to sharpen. One of our tests resulted in S30V cutting 14,000 linear inches of e-flute cardboard before notable edge wear against 12,000 for BG42. I have been completely satisfied with the performance of S30V
