Abstract: A golf club with a multi-piece adjustable and interchangeable modular hosel system comprises a shaft tip connector portion, an upper hosel portion, and optional, intermediate interchangeable hosel adjustment spacer(s). The modular hosel system can be used, for example, with no spacers in place, or one or more risers in each of the hosel adjustability regions. The adjustment spacers can be used to increase the hosel length and shaft axis to head center of gravity offset or intersection. Angled risers can be oriented to adjust the shaft axis relative to club head orientation to fit and adjust specifications including loft and lie angle, alone or in combination. The modular hosel construction provides a quick and efficient means of fitting the putter specification to a large number of golfer requirements and also adjusting the specifications for changing user needs or course conditions.

Abstract: A stand-alone putter structured and weight balanced enabling the putter to stand upright in a favorable lie and loft position on a putting surface without any outside support formed of a club head, a shaft connected to the club head, and having a gripping area at the upper end of the shaft. The club head is conventional in design and includes a ball striking face, a rear surface, a heel, a toe, an upper surface and a bottom sole structured to serve as a first ground support surface for the putter in a conventional use position with the bottom sole lying on a putting surface. The club head further includes at least one additional ground engaging support member extending outwardly from the club head forming a second ground support member to maintain the putter in a stand-alone position on the putting surface.

Abstract: A golf putter head with a front portion comprising traditional shape and appearance, with an integral face insert extending through the head to an alignment and weighting portion extending beyond the main body of the putter, adding improved alignment, increased moment of inertia (MOI) and adjustable weighting and adjustable balance and optimizable center of percussion. The putter head comprises a central face insert portion extending through the body and above the traditional weight flange, with mass relieved portions below the top of the alignment piece in order to receive one or more optional weights, and the upper side of the rearwardly extending portion being engraved or marked with various alignment indicia, and the whole through-head insert face portion and rearwardly extending portion being affixed to the base portion of the head at least in part with threaded fasteners.

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