    Abstract: A golf club is disclosed that has a golf club head with a face having peaks or ridges and deep grooves or valleys. The deep grooves or valleys promote improved “feel” and/or reduced “smash factor” which may be particularly desirable when the golf club head comprises a putter face. The deep grooves or valleys may eliminate the need for costly soft metal alloy faces and/or polymeric or other resilient inserts between the face and the body of the golf club head.

    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 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.
