ABSTRACT:
An arrow nock comprising a cylindrical body member having a plug shaft extending axially to one side for insertion within a tubular arrow shaft to maintain the shaft and nock in axial alignment. The nock is further provided with a grip portion which extends axially in the opposite direction from the plug shaft. The grip portion is flattened and merges with the cylindrical body member by way of an inclined surface. Disposed on opposite flat surfaces of the grip portion are pad portions facing in opposed directions and adjacent to a notch which receives the bow string. The pad portions are slightly elevated above the surface of the flattened portion. The pad portions have friction surfaces which help to grip the nock between the index and middle finger so that upon release of an arrow the incline surfaces tend to spread the finger tips and smooth surfaces adjacent to the pad portions and the recessed area at one side of the nock closest to the hand of the archer pass the fingers without engagement to minimize friction and enhance accuracy.
