Abstract: A golf club head includes a loft no less than 40 degrees; a striking face; a virtual center plane that is vertical and perpendicular to a virtual striking face plane and includes a face center; a rear face; and a recess. The recess extends in a heel-to-toe direction along an upper sole surface and has a depth that varies in the heel-to-toe direction such that a first depth corresponds with a first location heel-ward of the face center and a second depth corresponds with a second location toe-ward of the face center, the first depth being no less than 10 mm and greater than the second depth by at least 5 mm. An insert is received in the recess. And a center of gravity of the golf club head is spaced no greater than 5.0 mm from the virtual center plane measured in the heel-to-toe direction.

Abstract: A method of finishing an exterior surface of a golf club head includes providing a golf club head having an exterior surface that includes a first surface region, a second surface region, and a third surface region. The method further includes steps of applying a first surface finish to at least the third surface region, applying a first masking to at least the first and third surface regions, applying a second surface finish to the second surface region, removing the first masking, applying a second masking to at least the second and third surface regions, applying a third surface finish to the first surface region, and removing the second masking.

Abstract: A putter-type golf club head has a main body and a face component including a first element formed of a resilient material. The putter-type golf club head also has a second element forward of the first element and including a rigid material. The second element is secured directly to the first element. The first element has a thickness that gradually increases toward a sole portion of the club head.

Abstract: A putter-type golf club head is disclosed. When oriented in a reference position, the putter-type golf club head comprises a blade member and a central elongate member in communication with, and extending rearwardly from, the blade member. The blade member extends in a heel-to-toe direction and has a striking wall defining a substantially planar striking surface, and an upper surface of the central elongate member comprises at least one generally square-shaped alignment element.

Abstract: A method for use in a system implementing a reference golf club, one or more sensors associated with the reference golf club, and a computing device. Using the computing device, the method comprises receiving from the one or more sensors swing data relating to a swing of the reference golf club, analyzing the swing data to determine recommended shaft parameter values for each of a plurality of shaft parameters using an algorithm, accessing a shaft database comprising actual shaft parameter values for each of the plurality of shaft parameters for each of a plurality of shafts, determining at least one shaft from the plurality of shafts based, at least in part, on a comparison between the recommended shaft parameter values and the actual shaft parameter values, transmitting information relating to the at least one shaft; and displaying the information on a display of the computing device.
