A golf club head with a hollow therein comprises a face portion and a main body portion including a crown portion and a sole portion extending rearward from the face portion. The main body portion is provided with at least one slit penetrating through the main body portion. The slit has a width in the toe-heel direction and a length in the front-rear direction which is larger than the width. The surrounding area of the slit is at least partially provided with a thick portion.

A golf club grip may include a docking tube and an elongated handle. The docking tube may be configured to couple to a golf club shaft and may include a docking tube sidewall. The elongated handle may be detachably couplable to the docking tube. The elongated handle may include an elongated handle sidewall defining an axial opening configured to receive the docking tube. At least one of the docking tube sidewall and the elongated handle sidewall may include a projection and the other of the docking tube sidewall and the elongated handle sidewall may include a channel. The channel may be configured to receive the projection to prevent rotation of the elongated handle relative to the docking tube when the elongated handle is coupled to the docking tube.

A golf club head has a main body and a front recess that includes a flange. A rear portion of the main body includes a perimeter-weighting element. A striking face insert is secured within the front recess. A face center is located on the front surface of the striking face insert. A rear cavity is at least partially delimited by the perimeter-weighting element and a rear surface of the striking face insert. A rear insert is secured to the rear surface of the striking face insert. In an imaginary horizontal plane passing through a portion of the rear insert, proximate a heel portion of the club head, a heelwardmost point of the rear insert is spaced further from a vertical center plane than a minimum distance between the flange and the center plane. The club head comprises an auxiliary recess that extends outward from the rear cavity.

A golf club head includes a body, a recessed channel, and a weight assembly. The weight assembly has a weight, a cover, and a fastener coupling the cover to the body. The cover includes a first end, a second end, and a rabbet extending at least partially between the first end and the second end. The rabbet formed by at least two walls and sized and shaped to at least partially receive the weight and allow the weight to slide therein. One or more of the at least two walls have a retention rib extending therefrom. The retention rib is elongated in a direction between the first end and the second end and discontinuous in the elongated direction. The fastener is configured to move the cover between at least two positions, a first position whereby the weight is selectively slidable and a second position whereby the weight is secured.

A golf club head includes a body having a faceplate with a strike surface, a toe end opposite a heel end, a back end opposite the faceplate, and a sole opposite a top rail, the faceplate is connected to the sole and configured to pivot about the sole.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, the golf club head may include a face portion having a front surface and a back surface opposite of the front surface. A back groove extends on the back surface proximate to a periphery of the face portion and includes a first groove portion, a second groove portion transverse to the first groove portion, and a curved groove transition portion connecting the first groove portion and the second groove portion. The golf club head includes a body portion coupled to the face portion and having an interior cavity. A filler material is in the interior cavity and at least partially fills the back groove. Other examples and embodiments may be described and claimed.

Aspects of the invention are directed to golf club having a crown, a sole, a face, and a face alignment feature located on the face.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a body portion being hollow to define an interior cavity, a filler material in the interior cavity, and a face portion, which may include a face perimeter portion having a perimeter edge defined by a face toe edge, a face heel edge, a face top edge, and a face sole edge, a face recess portion on the back surface and having a recess perimeter portion at least partially surrounded by the face perimeter portion, and a plurality of back groove portions in the face recess portion. The plurality of back groove portions may extend proximate to the recess perimeter portion along at least 50% of the recess perimeter portion. Other examples and embodiments may be described and claimed.

A golf club head including a striking face, a back portion, and a back cover attached to the back portion, wherein the golf club head includes damping structures and materials to achieve desired acoustic characteristics.
