Embodiments of golf clubs with adjustable loft, lie, head mass and methods of manufacturing golf clubs with adjustable loft, lie, and head mass are generally described herein. Other embodiments can be described and claimed.

Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a method of manufacturing a golf club head may include providing a golf club head having a face portion. The method may include determining a reference characteristic time value at a reference location on the face portion, determining a measured characteristic time value at each of a plurality of locations on the face portion, determining a differential characteristic time value at each of the plurality of locations, and altering a face thickness at a location where the differential characteristic time value is nonzero. Other examples and embodiments may be described and claimed.

Disclosed herein is a golf club head comprising at least one crown opening and at least one crown insert attached to the body and covering the at least one crown opening. The golf club head further comprises at least one sole opening and at least one sole insert attached to the body and covering the at least one sole opening. The golf club head additionally includes at least one weight member configured to clamp first and second ledges at selected locations along a sliding weight track. The golf club head also comprise a coefficient of restitution (COR) feature located on the sole of the golf club head. The at least one crown insert is formed from a composite material having a density between 1 g/cc and 2 g/cc. The at least one sole insert is formed from a composite material having a density between 1 g/cc and 2 g/cc.

A golf club includes a shaft, a grip, and a club head. The shaft is coupled to the grip and to the club head. The club head includes a substantially rigid shell, a club face, and a contact area. The substantially rigid shell includes a conventional shape that has a toe area, a heel area, a sole area, a top area, and a back area. The club face is mechanically coupled to the substantially rigid shell to provide a face of the club head. The contact area is within the substantially rigid shell and positioned proximal to the club face. The contact area includes a plurality of force-focusing layers that functions to concentrate impact forces of the club head towards an area on the club face that makes contact with a golf ball during contact with the golf ball.

A golf club includes a golf club head having a body defining an interior cavity. The body includes a sole, a crown and a skirt positioned around a periphery between the sole and crown. A face defines a forward portion of the club head and includes a striking surface width and a hosel defining a hosel bore. A channel and a recessed port are positioned in the sole. The channel extends substantially in a heel-to-toe direction. A sleeve is mounted on a tip end of the golf club shaft and is adapted to be inserted into the hosel bore. A fastener has a shaft portion extending through a passage and a head portion located in the recessed port. Selectively attaching the sleeve adjusts at least one of a loft angle and a lie angle of the club head.

A golf club head is manufactured to form a cavity where the striking face of the golf club is secured to the sole and upper portion of the golf club head. A weighted composite is manipulated into a predetermined location within the cavity. The composite contains an adhesive which secures the composite within the cavity.

A golf clubhead that is designed with a unique inner and outer structure, using geometry and technology to provide super symmetry, harmony and balance at motion and at rest of golf swings. The triangular form clubhead does not require compensation during the swing thus allowing for greater repetition and simplicity of movement in turn producing performance benefits via consistency. The geometric triangular shape of the clubhead provides an instantly recognizable assistance in proper alignment at the rest position. The body of the clubhead may be hollow and feature inner symmetrical structures to complement the form of the body and to enhance and provide superior weight distribution and balance.
