I realize that I may be in the minority here, but does anyone else like having a flipper on their folder? Like the one on the CRKT M-16 or M-21? Or the Buck Vantage Pro? It looks like you could add one to the ESEE-3 folder and, once the blade was deployed, the flipper would be hidden under the finger guard.
Actually, I just took another look at the prototype and I'm not sure that's true. Regardless, I still like flippers (not sure why wave-style knives get so much more attention now) and I think the sheer ease of use and convenience would fit into the no BS utility approach of ESEE design without seeming like a gimmick.
