Abstract: A golf club head having a laser-generated features to create contrast on the club face of the golf club head. The club face includes a central region, a toe region, and a heel region. The central region includes a first plurality of laser-generated features that provide a height-intersection coverage of the central region, a width-intersection coverage of the central region, and a surface-area coverage of the central region. The laser-generated features increase the surface roughness value of the external surface of the club face by imparting micro-grooves that have an average groove depths of between about 45 ?m and about 60 ?m.

Abstract: A golf club head with a crown comprising an inner crown portion and an outer crown portion. The inner crown portion may be made of a low density or low elastic modulus material. The outer portion of the crown defines an opening to the cavity. The inner portion of the crown is attached to the outer portion of the crown such that the opening is covered by the inner portion of the crown.

Abstract: A multi-material iron type golf club head is disclosed. More specifically, the golf club head may have a first metallic portion, a second metallic portion, and a lightweight portion. The first metallic portion and the second metallic portion collectively define all external surfaces of the golf club head. The lightweight portion may be located within an interior cavity of the golf club head and may contact and support the striking face, the topline portion, the rear wall portion, and the sole portion of the golf club head.

Abstract: A golf club with a multi-material face is disclosed herein. More specifically, the golf club head in accordance with the present invention has a striking face portion that is backed by a composite layer. The multi-material face disclosed in accordance with the present invention may generally be manufactured via a bladder molding process that applies hydrostatic forces to the composite layer to create a more consistent bond between the composite material and the metallic material.

Abstract: A golf club head having a striking face having improved abrasion resistance by applying abrasion resistant material to the striking face. Applying abrasion resistant material to the striking face can include the use of electroplating a metal onto the striking face, such as chromium. The striking face can be co-molded with a conductive veil to improve the electroplating process. A physical vapor deposition layer can be further applied to the striking face. Alternatively, a veil can be applied directly to the striking face without electroplating. The veil can be made from compounds such as carbon, aramid, polyetherimide, polyphenylene sulfide, polyether ether ketone, polypropylene, and metals, such as copper.

Abstract: A small-format metal wood golf club head may include a first portion including at least a striking face formed of an alloy of titanium and a second portion including at least a portion of a sole formed of an alloy of steel. The golf club head exhibits beneficial characteristics of both titanium and steel in that the titanium striking face is lighter than a steel striking face having the same coefficient of restitution (COR) and the steel sole allows for concentration of mass in a beneficial location within the golf club head, while overcoming traditional difficulties in bonding titanium and steel.

Abstract: A golf club head may include a body, a back, a topline, a heel portion, a hosel, a toe portion, a sole, and a striking face. The striking face may include a plurality of scorelines, a base layer including fibers and a polymer matrix, a metal veil layer on top of the base layer, and a metal layer on top of the metal veil layer. The metal veil layer may include metal veils including metal-coated fibers.

Abstract: A co-forged iron type golf club is disclosed. More specifically, the present invention discloses a co-forged iron type golf club with the body portion made out of a first material and at least one weight adjustment portion monolithically encased within the body portion of the co-forged iron type golf club head without the need for secondary attachment or machining operations. The present invention also includes a combination of lightweight and heavy density weight adjustment portions that could be introduced towards the final forging step of the co-forging process, allowing for more flexibility in the selection of materials.
