Abstract: This invention is directed toward a lie adaptor that can be used to adjust an angel at which the shaft attaches to the putter. In one embodiment, the lie adaptor is inserted into the hosel of a putter, and then secured to both the shaft and putter head. In another embodiment, the lie adaptor has a cavity in its upper portion into which the shaft fits. In either case, the lie adaptor can be made with a variety of angle adjustments possible, such that a golf shop or even an individual golfer can quickly, accurately, and economically adjust the putter lie.

Abstract: This invention is directed toward a balancing device that can be used to find the balance center of a golf club head. It is specifically applicable to finding the “sweet spot” of putters. The device comprises a base portion that holds the device in place, and a fulcrum portion, upon which the head is placed and moved back and forth until it is balanced. The section of the golf club directly above the fulcrum is thereby found to be the center of the club, with an even amount of weight distributed on either side of the fulcrum. This allows a golf club manufacturer to accurately place a line on the golf club head that guides the golfer to the ideal portion of a golf club that should strike the ball.

Abstract: A golf club with an insert located in an ideal position to strike a golf ball. The head of the golf club and the insert have a built-in locking mechanism such that the insert is removable; the golfer can replace it with an insert of a different material, thereby changing the “feel” of the golf club through changes in the hardness/softness and density of the material from which the insert is made. The insert is screw-shaped with a flat head that is flush with the striking surface of the golf club when it is fully inserted. There is, optionally, an o-ring that slips over the threaded portion of the insert such that when the insert is screwed into the receptacle, the head is “padded” against the receptacle, thereby cushioning the impact and reducing the chances that the insert will rattle out of the receptacle due to frequent ball striking.
