Abstract
Abstract A grip for use on the extending end of the shaft of a golf club is provided with an especially configured array of longitudinally extending grooves which are in direct opposition to the rotation of the golf club about the longitudinal axis of the golf club shaft to resist twisting of the golf club in the golfer's hand resulting from mis-hitting of a golf ball in an off center location toward the toe or heel of the golf club head. The grip may have a visual indicator by which the rotational position of the golf club when being held in a golfer's hands can be determined by visual alignement of the grip with the golfer's hands.
