Abstract: The invention provides a new type of putter for golfers to improve their putting accuracy and stability. The grip is shaped to help users lock all joints on their hands and arms in place, and thus limits golfers movement of those muscles. By locking all joints and muscles, golfers can concentrate on using only the back and shoulder muscles to putt, making it much easier to have the putter face perpendicular to the intended golf ball path on the x-y plane. Not only would this allow more accurate, stable putts, with repeated usage of this device, golfers will become accustomed to using their back and shoulder muscles to putt, and hence improve their putting skill even with a regular putter.

Abstract: A golf club grip system is presented comprised of golf club grips of identical weights regardless of their grip thickness. The identical weight may be maintained by altering the grip material compound, grip construction method, or by varying the length of the grip along the golf club shaft as the grip width is varied.

The system is designed to permit pre-manufactured golf club grips to be selected by grip thickness and feel, while remaining identically weighted to all other possible thicknesses. This uniform weighting removes the need to adjust club head weight or perform dynamic or static swing weighting after grip thickness is selected.
