When is 20CV going to kick in? Rick Hinderer uses it, and SOG has used it sparingly in fixed blades, but nobody else.
I voted for zdp-189 because it just outcuts everything I have tried, and with the three zdp knives I've had, there has been no real problems with either breakage or chipping. If you remember that the purpose of a knife is to cut, it's hard not to choose zdp.
That said, I still have a little more faith in S30V when it comes to toughness, just based on what I've read. My main EDC is still S30V.
