ABSTRACT:
The swing of a golf club is changed by adding an additional weight, the center of gravity of the additional weight being at or below the center of gravity of the hand position on the gripping region of the club to provide a positive lever action for the club in the first cocked movement of the swing substantially the same moment of inertia in the first phase of the downswing wherein the golfer's hands are in the cocked position as conventional clubs and to provide a reduced moment of inertia for the club in the second uncocked movement of the swing between the uncocking of the golfer's hands and the striking of a golf ball.
