Abstract
A golf putter has a putter head having forward, rearward, top and bottom surfaces, and opposite ends. A cavity opening is centrally located in the top surface of the putter head. An elongated shaft with a ball on the lower end thereof extends into the cavity. A detent on the ball engages a detent in the bottom of the cavity to prevent the longitudinal axis of the golf shaft from forming an angle of less than 10 degrees with a vertical axis extending upwardly from the cavity and the putter head. The shaft is locked within the putter head by three screws. Two opposite screws extend into the cavity from a threaded longitudinal bore which extends through the putter head. A second transverse screw extends into the cavity through the putter head. When tightened, the three screws mechanically lock the ball on the lower end of the shaft in the desired position. Weight elements are placed in the longitudinal bore through the putter head, and screws in the outer ends of the bore bear against the balls to fix them into position within the bores. The density of the balls can vary to permit a plurality of weight distribution characteristics.
