i think i read this from the benchmade site and just concluded it was a slightly altered stainless that was similar enough to 440c to exempt it.
N680: A chromium-molybdenum conventionally produced stainless steel with the addition of vanadium and nitrogen. Excellent corrosion resistance properties, especially in salt water. Good hardenability and high obtainable hardness. High wear resistance and ability to preserve keenness.
N690: An Austrian made stainless steel, which is comparable to 440C in performance and value. Keen edge qualities with great corrosion resistance.
these are benchmade's exotic steels.
154CM: An American made premium grade stainless steel originally developed for tough industrial applications. Known for its best all-around qualities, it offers great corrosion resistance with good toughness and edge quality.
S30V: An American made and developed premium grade stainless steel created especially for knives. It is a powder made steel with a uniform carbide distribution and clean steel properties. As a blade material it offers excellent corrosion resistance and superb edge qualities.
CPM-M4: Special purpose, high-speed steel with a combination of high Carbon, Moly, Vanadium and Tungsten for excellent wear resistance and toughness; A powder-metal, non stainless steel.
