A putter comprising an adjustable hosel structure is disclosed herein. In particular, the putter comprises a hosel assembly comprising a shaft receiver and two interlocked bars that connect the shaft receiver to the putter head. A plurality of bolts connect the bars to the shaft receiver and the putter head, and these points of connection are joints about which the bars move, and which can be restrained to immobilize the hosel assembly or otherwise reversibly fix it in place so that a longitudinal shaft axis is aligned with a desired portion of the putter head. The hosel assembly preferably is adjustable along a horizontal, heel-to-toe axis, and is partially disposed, and secured, within a pocket on the heel side of the putter head.

An adapter to connect a straight golf shaft with a golf club head includes: a first end that is cylindrical and that is configured to be joined with the golf club head; and a second end that is connected to the first end, that is cylindrical, and that is configured to be joined with a tip end of the straight golf shaft, where an angle between (a) a first plane through a first axis of the first end and (b) a second plane through a second axis of the second end is between 0.5 degrees and 45 degrees.

A golf putter includes a putter head, a connecting member, and a main body. The putter head is made of metal. The connecting member includes a positioning seat, a first joining shaft extending from a bottom end of the positioning seat along an axis, and connected to the putter head, and a second joining shaft extending from a top end of the positioning seat along the axis. The positioning seat has a width that is perpendicular to the axis and that is larger than a width of the first joining shaft perpendicular to the axis and a width of the second joining shaft perpendicular to the axis. The main body is made of carbon fiber, and has a tubular wall formed with a connecting groove. The second joining shaft is inserted into the connecting groove.

A golf putter includes a putter head and a shaft. The putter head includes a toe end and a heel end, a putter face, a first part, a pair of connecting pins, and a second part. The second part is coupled to the first part via the pair of connecting pins such that the putter head defines a center of gravity of the putter head in a plane that is parallel to a vertical plane containing the putter face and that passes through the pair of connecting pins. Further, a bottom end of the shaft is coupled to the second part of the putter head at a contact point that lies between the toe end and the heel end of the putter head and that lies behind the center of gravity with reference to the putter face, and a top end of the shaft is inclined towards the vertical plane.

Apparatus and methods are described herein to provide a golf club, such as, for example, a putter, with a select loft angle and/or a select lie angle. In some embodiments, an apparatus includes a golf club having a golf club head, a hosel, and a hosel shim. The golf club head has a hosel shank and the hosel is configured to be coupled to the hosel shank. The hosel shim is configured to be coupled to the hosel to position the hosel at a select angle relative to the golf club head such that the golf club has a select lie angle. The hosel shim is further configured to limit rotational movement of the hosel relative to the golf club head such that the select lie angle is maintained when the hosel is coupled to the golf club head.

A golf putter includes a putter head and a shaft. The putter head includes a toe end and a heel end, a putter face, a first part, a pair of connecting pins, and a second part. The second part is coupled to the first part via the pair of connecting pins such that the putter head defines a center of gravity of the putter head in a plane that is parallel to a vertical plane containing the putter face and that passes through the pair of connecting pins. Further, a bottom end of the shaft is coupled to the second part of the putter head at a contact point that lies between the toe end and the heel end of the putter head and that lies behind the center of gravity with reference to the putter face, and a top end of the shaft is inclined towards the vertical plane.

Disclosed herein is a golf club head that comprises a body. The body comprises a sole portion, a crown portion, a skirt portion, and a face portion, positioned at a forward region of the golf club head, opposite a rearward region of the golf club head, and extending from a toe region to a heel region of the golf club head. At least a portion of the body is made of a titanium alloy. The golf club head also comprises a large weight, coupled to the sole portion of the body and made of a steel alloy. A mass of the large weight is at least 40% of a mass of the portion of the body made of the titanium alloy. A total mass of the large weight and the portion of the body made of the titanium alloy is at least 210 grams.
