Disclosed herein is a golf club head that comprises a body. The body comprises a sole portion, a crown portion, a skirt portion, and a face portion, positioned at a forward region of the golf club head, opposite a rearward region of the golf club head, and extending from a toe region to a heel region of the golf club head. At least a portion of the body is made of a titanium alloy. The golf club head also comprises a large weight, coupled to the sole portion of the body and made of a steel alloy. A mass of the large weight is at least 40% of a mass of the portion of the body made of the titanium alloy. A total mass of the large weight and the portion of the body made of the titanium alloy is at least 210 grams.

A golf putter includes a putting head including a putting head body, configured with a flat bottom surface, a rear ward angled hose) aperture and a rear angled flat surface; left and right indentations for receiving weights, and left and right detachable wheels attached on sides of the putting head body, such that the putting head is configured to be slidable along a putting surface to enable a golfer to line up the putting head, a golf ball, and a target cup in a front of the golfer, in order to hit the golf ball with a forward sliding motion of the putting head.

A golf club comprising: (a) a head having a face configured to make contact with a golf ball; (b) an extended portion extending from the head free of obstructing the face; and (c) a hosel movably secured to the head, wherein the hosel is configured to rotate relative to the head, or vice versa; wherein the rotation of the hosel relative to the head, or vice versa, changes the golf club between a left-handed position and a right-handed position.

A shaft insert (or external connecting segment) with greater flexibility than the substrate shaft allowing for a more flexible zone in an area of separation between two separated portions of the substrate shaft. The flexible connection is intended to be installed between two segments of the separated substrate shaft primarily on a golf putter with the flexible connection within 5 inches of the base of the club in total compliance with USGA (United States Golf Association) Rule 2, Appendix II. 2. b. requiring any change from the continuous shaft be within 5 inches of the club base. The shaft flex connection is designed to be symmetrical around its cross section with equal flexibility and torsional displacement in all directions in compliance with USGA Rule 2, Appendix 2. c. requiring golf shafts to be equally flexible with equal torsional displacement in all directions. The preferred embodiment of the invention utilizes a flexible tube for which the outside diameter is slightly smaller than the inside diameter of the substrate shaft. The substrate shaft is separated at the top of the hosel of the club and joined by fixing the tube (with epoxy or other adhesive) in each section of the separated sections of the substrate shaft whereby the separation is maintained at a fixed distance by installing an O ring or other spacer over the insert tube and between the two segments of the substrate shaft.

A golf club may include a rear surface having first branding indicia, and a predefined region defined at least in part by a partially raised surface, a fully raised surface, a partially sunken surface, a fully sunken surface, a stepped surface, a textured surface, and a partially raised/partially sunken surface. The first branding indicia may be inside the predefined region. The golf club may also include a weighted tape with a second branding indicia placed on the rear surface of the golf club, preferably with a portion of the weighted tape being inside the predefined region.

A golf club has within the grip a main device, a connector, a wireless module, an antenna, a light emitting element, and an optical fiber. The main device is a device that includes a sensor such as a motion sensor, a circuit such as a CPU, and a battery. The light emitting element is an indicating means that emits light in accordance with the state of a component mounted in the golf club. The light emitted by the light emitting element is guided to the grip end by the optical fiber and emitted to the outside of the grip via the grip end.

Golf clubs and golf club head structures having an indicator providing a visual indication of a location of a center of gravity of a wood-type golf club are presented. The indicator may include a central portion or hub that is generally aligned with the center of gravity of the club. The indicator may also include a plurality of legs extending outward from the hub toward a perimeter of the golf club head. In some arrangements, the indicator may be formed to distribute a portion of the weight of the club head in order to adjust or move the center of gravity of the club head, in addition to providing a visual indication of the location of the center of gravity.

A novelty golf club in the form of a putter is disclosed. A conventional putter is adapted to include a battery assembly disposed in the grip end of a club shaft. The battery assembly includes a set of batteries arranged end to end. A pair of terminals are configured at the battery assembly adjacent a first coupling element. A powered accessory has a second coupling element which cooperates with the first coupling element to releasably secure the powered accessory to the battery assembly. A variety of powered accessories, such as a fan assembly, a mixer assembly, a string trimmer assembly, a vibrating massager, a flashlight, and a charging unit are configured for the novelty golf club.

A golf club includes a shaft, and a club head provided at an end of the shaft, wherein: the club head includes a head body and plate-like face member provided as a hitting face of the head body; and the face member is fixed to the head body only at a part of an upper or lower edge surface, or parts of both upper and lower edge surfaces of the face member. A fixing position of the face member may be located in the proximity of a node of a characteristic vibration in a case of freely supporting the face member. The Rockwell C-scale hardness of the face member is preferably no less than 40. The face member may be fixed to the head body by a set screw, at two locations of the upper edge surface, and two locations of the lower edge surface of the face member.
