Abstract: The blade of a folding knife has a tang portion by which the blade is pivoted to a handle for swinging between an open position and a closed position. In the open position the blade extends from the handle with its sharpened edge exposed for use, whereas in the closed position the sharpened edge is received in a groove of the handle. A locking link is pivotally mounted on the handle for swinging in the same plane as the blade, with a swinging end of the locking link cooperating with a notch in the tang to automatically lock the blade in the open position. The blade can be released for movement to the closed position by manipulation of buttons exposed at the exterior of the handle, which buttons extend transversely from the swinging end portion of the locking link.
