Just for the record: You do not have to release the Axis lock first to flip open your knife. Quite the opposite: my 710 Axis is the easiest-to-flick knife I have. And it locks up like a prison.
You can flip open just about any knife, including lockbacks like my Spyderco Calypso Jr., if you hold the knife such that the butt end (the one that contains the point of the blade) moves in an arc--rather than holding it such that the pivot end moves in an arc.
