An American steel from Crucible, CPM-S90V is one of the top super steels of today. It features incredible edge retention and wear resistance, and very high corrosion resistance. It is a very expensive steel, and only comes in top of the line knives. CPM-S90V's extreme wear resistance is due the incredible amount of Vanadium in the alloy, and as a result it can be very difficult to grind or sharpen.
