An object is to provide an iron golf club head that has high drainage performance and facilitates application of backspin also in a wet state. In an iron golf club head including a plurality of scorelines in a face surface, a microgroove including at least an inclined groove is included between the scorelines, the microgroove extending in a heel leading edge-toe top edge direction to be connected to an upper scoreline.

A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head includes a front portion. A face portion is coupled to the front portion. The face portion includes a central strike portion and a perimeter. A plurality of projections extend from the face portion to provide a ball striking surface for impacting a golf ball. Each projection is defined by a plurality of grooves intersecting one another within the face portion. The plurality of projections are each defined by an area ratio between a base portion area and a peak portion area. The area ratios of the plurality of projections decrease from the central strike portion to the perimeter of the face portion. Other examples may be described and claimed.

A golf club having unique mass properties and all the benefits afforded therefrom.

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 toe region includes a second plurality of laser-generated features that provide a height-intersection coverage of the toe region, a width-intersection coverage of the toe region, and a surface-area coverage of the toe region. The heel region includes a third plurality of laser-generated features that provide a height-intersection coverage of the heel region, a width-intersection coverage of the heel region, and a surface-area coverage of the heel region.

Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.

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.

Described herein are embodiments of golf club heads having a balance of the following parameters: a low and back club head center of gravity position, a high moment of inertia, a large Ixy product of inertia, and low aerodynamic drag. Methods of manufacturing the embodiments of golf club heads having a balance of club head center of gravity position, moment of inertia, product of inertia, and aerodynamic drag are also described herein.

A golf club head includes a golf club head main body having a toe, a heel opposite the toe, a sole, and a top portion opposite the sole. The golf club head further includes a striking face having a face center. The striking face includes a central region including the face center, a first average thickness, and a variable thickness. An upper region above the central region has a second average thickness and a toe region toe-ward of the central region has a third average thickness. An intermediate region at least partially surrounds the central region and is disposed between the central region and each of the upper region and the toe region. The intermediate region has a fourth average thickness that is greater than the first average thickness, the second average thickness, and the third average thickness.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion with a toe portion, a top portion, a sole portion, and a back portion. The back portion may be include a back wall portion. The golf club head may also include a face portion, an interior cavity, at least one weight portion, and at least one port. The interior cavity may be partially or entirely filled with a polymer material. Other examples and embodiments may be described and claimed.
