A golf club, in particular a driver, comprises a pivotal coupling (4, 5), by means of which the club head (2) can be rotated about a vertical rotation axis (7) in respect to the shaft axis (3) and be held in a plurality of finely grained angular positions. The angle (β) between the rotation axis (7) and the shaft axis (3) corresponds approximately to 90° minus the lie angle of the golf club, while the angle (γ) between the rotation axis (7) and a tangential surface of the club face (22) corresponds approximately to the loft angle of the golf club. This ensures that rotation axis (7) is substantially vertical to the ground for the correctly held club. Therefore, the pivotal coupling (5, 6) can be used to correct the face angle and therefore to easily correct for a player' s tendency to use the club with its club surface in closed or open position. Thus, a player can easily correct his mishits of slices or hooks without changing the loft angle or lie angle. |
