well.. because the axis keeps the blade closed, there is a space where it will be "sucked" back into the handle, but not nearly as stiffly as a lockback. You don't have to disengage the lock to open the knife.. The mechanism is VERY fluid with little resistance.. maybe more than a linerlock's detent, buy definitely less than a back lock like a spydie. My ONLY gripe with the Axis is the "Omega" spring... it is flimsy, but doubtful that there would be a problem. I'd say that all things considered, the Axis is tried and true, and I would trust my precious guitar playing fingers with it any day. I like liner style locks better (easier for me to close), including the frame lock, but I believe that the Axis will wear better with time, and, over time, do a better job of keeping the blade from opening accidentally. YMMV.
