Abstract

A folding knife of the type wherein the blade may be moved between open and closed positions with the hand holding the knife. A blade is connected by a fixed pivot pin to a casing having the usual two handle or cover pieces providing a casing with a space for receiving the blade in the closed position. A substantially V-shaped slot extends through one of the cover pieces in close proximity and partially surrounding relation to the pivot pin. In addition to a circular opening for the pivot pin, the blade tang includes a linearly elongated, through slot communicating at one end with the circular opening. An actuating member, having integral head and stem portions, extends through the V-shaped slot in the cover piece and slidingly engages the slot in the blade tang, and into a blind V-slot in the inwardly facing surface of the other cover piece. The head of the actuating member may be manually engaged by the operator and moved from one end of the V-shaped slot to the other as the stem portion engaging the tang slot moves the blade about the pivot pin between open and closed positions.
