I saw the 20CV and was tempted. I have a PM2 in S110V and yep like you said not fun to sharpen, but it does hold an edge!
Just received a response to my post on Spydercoforums, "Selfish request for another Manix 2 in M390 or 20CV" and got an exciting response. You might like to head on over there for a look.
Thank you again John!
