  • Putter head assembly
    Patent number: 6217459
    Abstract: A putter head assembly (2) includes a generally S-shaped hosel (4) having first and second ends (6, 8). A putter head (14) extends from the second end of the hosel. The hossel and putter head are made as a one-piece unit from a polymer material, typically a thermosetting resin. A golf ball-striking faceplate (16) is mounted to the putter head. These features combine to create a desirable feel to the golfer upon contact with the ball.
