SC10PGRE Spyderco Endura Dark Green ZDP189 Pocket Knife

I have this knife (well, the scales of mine are blue, but...) and it has its pros and cons. ZDP-189 is a really hard steel, RC 67 (!). This blade simply doesn't get dull. Now the con -- it chips instead. So if you want a very sharp knife keeping an excellent edge, this is the right choice. But you won't be happy with it if you're after a workhorse.
