Abstract: A putter-type golf club head includes a striking face with a plurality of grooves having a variable depth profile and a variable pitch. Groove variation is tailored to correspond to the golf club heads' moment-of-inertia, mass, or another attribute. A surface treatment method includes selecting a variable depth profile and a variable pitch for a plurality of grooves and surface milling a striking face of a golf club head to form the plurality of grooves.

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 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 golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40°. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance D1 that is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.

Abstract: A method comprising, in a striking face of a golf club head, the striking face being formed of a first material having a first hardness, creating a plurality of initial grooves, the initial grooves having a first cross-sectional area (A1) and a first pitch (P1) such that A1/P1>0.0030 in. The method continues with modifying the initial grooves at least by positioning a second material in each of the plurality of initial grooves, the second material having a second hardness that is less than the first hardness, such that the first material and the second material form a plurality of final grooves each having a second cross-sectional area (A2) and a second pitch (P2) such that A2/P2

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.
