Has anyone heard of this steel before? It looks incredible! 3.45% carbon, 8% tungsten, 11.5% vanadium, 5% cobalt, 19% chromium, plus smaller amounts of other alloys. Is said to have the wear resistance of CPM 15V at 65 HRC, and the toughness and compressive strength of INFI. Also is said to have the rust resistance of CPM D2. Are there any downsides to this steel? It doesn't seem to have a tradeoff. Is spyderco willing to use this stuff on future knives?
