The steel difference
CPM-20CV
Crucible's answer to M390 and chemically near-identical to it. Superb edge retention and corrosion resistance, slow to sharpen.
CPM-M4
A high-speed tool steel run very hard. Edge retention is near the top of anything used in knives and it is tougher than most steels that cut as long, but the low chromium means it WILL rust if you put it away wet. Benchmade uses it on the Bailout where cutting performance matters more than corrosion.
