  • Patent number: 8529363
    Abstract: The self-attaching golf putter aid includes an upper grip joined at a pivot point with a bottom bracket such that the upper grip can rotate about a vertical axis with the bottom bracket. The bottom bracket is designed to attach onto the handle of a putter via an adjustable strap. The aid is used by grabbing the upper grip with a first hand while grabbing the bottom bracket and handle of the putter with a second hand, and wherein the end user holds the upper grip stationary while swinging the putter to form a true and smooth pendulum golf putting stroke that is ideal when putting.
