Abstract
The present invention provides a putter club 10 which minimizes the reaction from the golf ball 5 during putting, effectively and appropriately transmits the putting force to the golf ball 5, and provides an effective sense of putting distance. The present invention is characterized by the location of the center of rotation P (center of instantaneous impact or shock) of the putter club 10 during putting at a position on the grip 4 (especially locating it on the grip area 6), by this arrangement minimizing the reaction from the putter club to the hands, and by the location of the center of rotation P of the shaft 2 during putting on the grip 4, making it easy to control the entire putter club.
