Public service announcement: Thumb opening as I displayed in the video above is not a sustainable means to open the knife. I was able to do it no problem the first few times, but subsequent openings were hard on my thumb and thumbnail, even to the point where I drew blood from under the the thumbnail. So if anyone is considering this mod, and wants to open it one handed via thumb flick, think twice. However, if you want "wave" opening, it works flawlessly as long as you make sure to angle it correctly (as with any "waved" knife, of course). I will still carry this, clipless in my right front pocket and treat it as a two hand opener, or if I ever need the W.O.O. factor, then reverse grip edge out "waved" deployment will be perfect.
