A folding knife incorporates an opening assist mechanism that functions to drive the blade from the closed to the open position and to retain the blade in the closed position. In one embodiment a spring arm located to one lateral side of the blade interacts at its forward end with a drive pin on a tang portion of the blade during a part of the blade's rotational path. The spring arm applies pressure to the tang of the blade through the drive pin when the blade is closed. |
