| 摘要 |
A customized putter including a shaft bent adjacent the head with a reverse curve, and a head to which the shaft is mounted with a ball and socket joint so that the shaft may be moved orbitally relative to the head to secure the precise position or attitude which is best suited to the stance, address, and other features individual to the owner, face balancing the club in its determined attitude by rotation of the shaft on its own axis in its horizontal balanced position until the striking face is parallel to the ground, such that the center of gravity of the head is below the plane of the longitudinal axis of the shaft in the horizontal balanced position, and then irreversibly securing the head and shaft in the combined attitude and face balanced position. The club is not ready for United States Golf Association play unless and until it is irreversibly locked in the combined attitude and balanced position.
