Abstract: A golf club head that allows a user to customize the location of the center of gravity. The golf club head comprises a club head having a hollow cavity with a weighting port. The weighting port allows a user to place weighting material inside the hollow cavity, customizing the location of the center of gravity, the swing weight, the total weight, and the balance of the golf club.

Abstract: A relatively rigid golf club grip and a method for manufacturing a relatively rigid golf club grip. The method comprises machining the club grip from a metal or other generally rigid material including a butt and main body from a stock piece of material. The golf club grip also includes a tip portion that may, but need not be, made from relatively rigid material.

Abstract: Disclosed is a metal golf club head with optimum macro- and micro-structures and properties and a method for manufacturing a metal golf club head. The method comprises forging precisely a metal billet at a temperature between 35-47% of the melting temperature into a net or near-net lower portion shape comprising a face portion, a hosel portion, and an integrated sole and wall portion. The forging process is preferably performed in at least two stages, with the top stage forging a pre-form shape approximately equal to 60-80% of the final shape. The second stage of the forging process results in the net or near-net shape with only localized conditioning by machining or grinding. A crown portion is manufactured by stamping or forging, and then welded to the lower portion to form the metal golf club head.

Abstract: A golf club shaft for use in a golf club such as a putter. The shaft preferably comprises an over-sized hollow, circular tube having an outer diameter of at least 0.75 inches along substantially its entire length. In an alternate embodiment, the shaft includes a tapered intermediate section, and the tip end has an outer diameter of approximately 0.63 inches to accommodate an oversized club head.
