A golf club head comprises a sole, a recessed sole port in the sole; and a rotatably adjustable sole piece adapted to be at least partially received within the sole port and comprising a central body having a plurality of contact surfaces adapted to contact the sole port and being offset from each other along a central axis extending through the central body of the sole piece. The sole piece can be positioned at least partially within the sole port at five or more rotational and axial positions with respect to the central axis, wherein at each rotational position, at least one of said contact surfaces of the central body contacts the sole port to set the axial position of the sole piece. The sole port and/or the sole piece can be generally pentagonal in shape.

A golf club head that includes a plate opening, a plate-opening recessed ledge defining the plate opening, and a strike plate attached to the plate-opening recessed ledge. The golf club head also comprises a hollow interior cavity. At least a portion of a top half of the plate-opening recessed ledge is made of a first material having a first density and at least a portion of a bottom half of the plate-opening recessed ledge is made of a second material having a second density that is greater than the first density. The top half of the plate-opening recessed ledge is closer to a crown portion of the golf club head than the bottom half of the plate-opening recessed ledge and the bottom half of the plate-opening recessed ledge is closer to a sole portion of the golf club head than the top half of the plate-opening recessed ledge.

A golf club head that comprises a hollow interior cavity, a first piece, a second piece, adhesively bonded to the first piece along a first bonded joint, a third piece, adhesively bonded to the first piece along a second bonded joint, and a fourth piece, adhesively bonded to the first piece along a third bonded joint. A volume of the golf club head is at least 120 cubic centimeters (cc) and at most 600 cc. The first bonded joint has a first-joint bond area. The second bonded joint has a second-joint bond area. The third bonded joint has a third-joint bond area. A summation of the first-joint bond area, the second-joint bond area, and the third-joint bond area is at least 1,950 mm.sup.2 and at most 3,400 mm.sup.2.

A shaft for a golf club includes a first end, a second end, and a demarcation. The first end is adapted to attach to a club head. The second end is adapted to receive a grip distal to the first end. The demarcation is positioned at or adjacent to the balance point of the golf club between the first end and the second end.

A method of making a golf shaft, and a shaft made thereby, for connection to a golf club head including a first upper section having a first diameter and an upper butt end; a second lower section having a second lesser diameter than said first diameter and a having a lower tip end for connection to the golf club head; and, a gradually tapering intermediate section connected between the first upper section and the second section that reduces the outside diameter of the shaft from the diameter at the upper section to the diameter of the lower section. The location of the intermediate section relative to the upper butt end of the shaft is determined by a weight value of the shaft such that as the weight of the shaft becomes lighter, the tapered intermediate section is located closer to the upper butt end of the shaft and the tapered intermediate section is located further from the upper butt end of the shaft as the shaft becomes heavier.
