A golf club head including a weight mount disposed on the sole, a weight member configured to reside in the weight mount, a compressible member residing between the weight member and the weight mount, wherein the weight member comprises a longitudinal axis about which the weight member is configured to rotate, the weight member comprising projections extending radially outwards from the longitudinal axis, wherein the weight mount comprises circumferential ramps, wherein rotation of the weight member about the longitudinal axis forces the projections along the circumferential ramps, wherein the weight member goes from an unlocked position to a locked position in less than one full turn of the weight member relative to the weight mount, wherein rotation of the weight member compresses the compressible member, wherein the circumferential ramps comprise detents, wherein the projections are configured to reside in the detents when the weight member is in the locked position.

A configurable golfing apparatus including a rectangular handle portion with plural components. The rectangular handle portion is placed over an existing golf club shaft. An end camp damper is placed on a top end of the rectangular handle portion. The rectangular shape provides new and additional hand placement and new and additional configuration capabilities for both right handed and left handed golfers. The rectangular handle portion includes plural support and shock absorbing components in plural different configurations providing optimal force absorption and optimal shock absorption. The configurable golfing apparatus allows easy retrofits on existing golf club shafts compliant with United States Golf Association (USGA) rules.

An aerodynamic sporting item, such as a tennis racket, is provided. The item includes a plurality of ridges on a surface of the sporting item. The ridges are aligned with a direction of flow of air across the sporting item when used. The ridges define channels between adjacent pairs of ridges and a plurality of dimples are located in the channels defined by the ridges.

Methods of manufacturing a golf club head comprising one or more stiffening members proximate the face, and particularly solid rods or a plate with one or more cutouts, is disclosed herein. One method comprises the steps of preparing a wax mold of a golf club head including a plate stiffening member with excess material, casting the golf club head, and machining away the excess material. Another method comprises the steps of casting a golf club body, providing a plate stiffening member, providing a face component such as a face cup, tack welding the plate stiffening member and the face component to the golf club body, and welding these parts together.

A hollow golf club head comprises a face part, a sole part, a side part, a crown part, and a hosel part. At least one of the face part and the crown part has portions of two different rigidities that are first and second rigid portions, the first rigid portion has a first rigidity, the second rigid portion is made of the same material as the first rigid portion, and the second rigid portion has the same thickness as the first rigid portion but has a lower rigidity than the first rigidity of the first rigid portion.

A golf club head comprises a head main body, a weight member and a fixing member. The head main body is provided with a concave portion concaved from an outer surface of a finished shape of the golf club head. A specific gravity of the weight member is larger than a specific gravity of the head main body and larger than a specific gravity of the fixing member. The weight member is at least partially disposed in the concave portion. The fixing member is fixed to the concave portion so as to cover at least a part of the weight member from outside of the golf club head. The fixing member is provided with a through hole having an opening located in the above-said outer surface, and a part of the weight member is disposed in the through hole.

A golf club head that is capable improving on the inertia properties of a golf club head all while also improving the Center of Gravity (CG) location is disclosed herein. More specifically, the golf club head in accordance with the present invention achieves a relative low Moment of Inertia (MOI) about the Z-axis (MOI-Z) as well as a relatively low MOI about the Shaft-axis (MOI-SA), all combined with a high MOI about the X and Y-axis (MOI-X and MOI-Y).

Embodiments of putter-type golf club head comprising a striking surface capable of achieving consistent ball speeds across the striking surface to account for various ball impact locations are described herein. The striking surface has at least two materials that differs in concentration away from the geometric center of the striking surface to provide this consistency. Consistent (or uniform) ball speed is achieved throughout the striking surface as the portion of the golf ball that contacts the striking surface interacts with at least two materials having a differing material characteristic.

A golf club head includes a club face and a body. The club face is formed from a metallic material and includes a first, hitting surface, a second, rear surface that is opposite the first surface, and a flange that is separated from the second surface by a transverse distance. The body is formed from a polymeric material and includes a crown, a sole, a hosel, and a face support. The club face and the body cooperate to define a closed volume, and the face support extends to opposing sides of the flange and is operative to couple the club face to the body.
