I never heard of this steel before learning of the Spyderco Southard. I'm really interested in the Southard, its just way above my price range. I'm still curious about the steel though. I know nothing of metallurgy and have little experience with steels (the steels I do have experience with are medium-ish grade steels: 420HC, AUS8, Sandvik 14c28n etc.) So hows the edge retention, rust resistance, wear resistance, hardness, toughness, and sharpenabilty of CTS 204P? Thanks for any input you may have :D.
 
It is fantastic steel. It is basically the same as Bohler M390 or Diratech 20CV. It's probably one of my favorite steels. See Ankerson's thread in the testing sub forum. It will answer all your metallurgy questions.

Of all the steels you mentioned, they aren't even in the same class as CTS 204p. It's 20% chromium, 4% vanadium, 1.7-1.9% carbon (don't remember exactly). So, it's darn good steel. All those numbers are pretty close, I'm going from pure memory. :)

CTS-204P is awesome. It is easily one of my favorite steels. It will blow all of the steels that you've listed out of the water in every area.

Hmmm...I never realized 14C28N had that edge retention that good. My Blur seemed to dull pretty quickly, I don't remember what I cut with it though (may have been cardboard). It sharpened very quickly on the Sharpmaker though.
