David,
My Chive looks exactly like this at the bottom and it is from very first run, I'm not certain pre-production or prototype. I have got it as gift from Douglas Flagg (KERSHAW) at IWA show in Nuremberg, March 2001. The regular production wasn't set up then yet.
If the bottom knife at the picture is from the same run it should have KERSHAW logo on the clip.
Nice picture Jeff, thanks!
