The present invention relates to a golf club with an adjustable shaft angle and a method of adjusting the same. More specifically, the invention provides a golf club head, a rotating mechanism and a shaft. The rotating mechanism comprises a sphere easily rotatable within predetermined limits so that the angle of the shaft may be adjusted to desired values which fall under the restrictions of golfing ruling authorities. A method is also provided so as to adjust the angle of the above-mentioned shaft.

A configurable golfing apparatus including a rectangular handle portion with plural components. The rectangular handle portion is placed over an existing golf club shaft. An end camp damper is placed on a top end of the rectangular handle portion. The rectangular shape provides new and additional hand placement and new and additional configuration capabilities for both right handed and left handed golfers. The rectangular handle portion includes plural support and shock absorbing components in plural different configurations providing optimal force absorption and optimal shock absorption. The configurable golfing apparatus allows easy retrofits on existing golf club shafts compliant with United States Golf Association (USGA) rules.

A putter head comprising a removable and replaceable hosel is disclosed herein. In particular, the putter comprises a first body portion with a plurality of protrusions, a second body portion with a plurality of cavities sized to receive the protrusions, a hosel with an engagement portion that is trapped within one of the cavities by a protrusion, and a mechanical fastener to removably fix each of these pieces together. The fastener preferably extends through a bore on the heel side of the putter head and into a threaded bore within one of the protrusions. In an alternative embodiment, the putter head has a single body portion, which receives the engagement portion of a hosel in a heel side cavity, and which is affixed to the hosel via a fastener that extends through a front surface of the body portion.

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.
