Abstract: A putter-type golf club head has a top portion, a bottom portion, a heel portion, a toe portion, and a striking face having a variably textured region. The variably textured region includes a central portion and an outer portion laterally spaced from the central portion towards one of the heel portion and the toe portion. The central portion has a material ratio of less than 20% at a cutoff height of 0.1 mm and the outer portion has a material ratio greater than that of the central portion at the cutoff height of 0.1 mm. Variation of the textured region provides consistent ball speed upon impact at different lateral positions of the striking face.

Abstract: A putter-type golf club head that, when oriented in a reference position, includes a rear portion in communication with, and rearward of, a blade portion and having a rear portion top surface. The club head also includes a projection extending upwardly from the rear portion top surface, the projection having a projection top surface, a heel-ward side surface, a toe-ward side surface, and a rear surface, the projection top surface comprising a generally planar surface. And the club head further includes a sightline formed in the projection top surface and that comprises a groove at least partially filled with a filler material having a visually contrasting appearance to portions of the top surface surrounding the groove, the groove defining a virtual center line segment oriented in a substantially front-to-rear direction at a substantially constant height from a lowermost point of the sole between 16 mm and 26 mm.

Abstract: A putter-type golf club head that, when oriented in a reference position, includes a blade portion having a striking face, a top line, and a sole, the striking face in turn including a face center. The club head further includes a rear portion in communication with, and rearward of, the blade portion, and it includes an alignment element rearward of, and recessed toward the sole from, the top line. The alignment element defines a virtual center line segment oriented in a substantially front-to-rear direction at a height between 19 mm and 24 mm from a lowermost point of the sole, the center line segment having a length no less than 34 mm and being not spaced more than 10 mm from a virtual vertical plane passing through the face center and extending generally perpendicular to the striking face. A width of the club head is no less than 3.0 in.

Abstract: A golf club head includes a striking face, a sole portion, a top portion, a hosel, a rear surface, a loft no less than 40°, a virtual vertical plane, and a center of gravity. The striking face has a face center, a leading edge, and a virtual striking face plane. The hosel includes an internal bore configured to receive a golf shaft and includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf shaft. The rear surface is opposite the striking face and has an upper portion and a lower portion, the lower portion including a forward-extending recess. The insert covers the recess forming a hollow portion. The virtual vertical plane is perpendicular to the striking face plane and passes through the face center. The center of gravity is spaced a distance from the virtual vertical plane in the heel-to-toe direction.

Abstract: A grip for a putter-type golf club including a bottom end having a recess to receive a golf shaft, and a top end opposite the bottom end. The recess defines a longitudinal axis, and an exterior side surface extends about the circumference of the longitudinal axis. The exterior side surface defines a generally planar portion and a generally arcuate portion adjoining the planar portion. A grip cross-section no greater than 15 mm from the top end includes a planar portion cross-sectional width no less than 4 mm, a first cross-sectional length, L1, and a maximum cross-sectional width located at a depth D1 from the planar portion such that D1/L1 is no greater than 0.40. According to another aspect, a grip cross-section between 120 mm and 140 mm from the top end includes a cross-sectional maximum width, W3, and a cross-sectional length, L3, such that W3/L3 is no greater than 0.90.
