Rockstub
Punches above its weight in terms of build quality - it's very solid with a smooth action. The contours make the handle feel very secure in the hand, but the handle is stubby (as the name suggests). Opening seems to require more of a flick than a slow push on the thumb stud, and locking seems secure. Unfortunately I had to drill out a stuck screw to remove the pocket clip, despite it seeming re-positionable.
