The grip consists of material added to the shaft to enable the player to obtain a firm hold. The grip must be fixed to the shaft, must be straight and plain in form, must extend to the end of the shaft and must not be moulded for any part of the hands. If no material is added, that portion of the shaft designed to be held by the player must be considered the grip.
(i) For clubs other than putters the grip must be circular in cross-section, except that a continuous, straight, slightly raised rib may be incorporated along the full length of the grip, and a slightly indented spiral is permitted on a wrapped grip or a replica of one.
(ii) A putter grip may have a noncircular cross-section, provided the cross-section has no concavity, is symmetrical and remains generally similar throughout the length of the grip. (See Section 3b(ii) explanation in the interpretations).
(iii) The grip may be tapered but must not have any bulge or waist. Its cross‑sectional dimensions measured in any direction must not exceed 1.75 inches (44.45 mm).
(iv) For clubs other than putters the axis of the grip must coincide with the axis of the shaft.
A putter may have two grips provided each is circular in cross-section, the axis of each coincides with the axis of the shaft, and they are separated by at least 1.5 inches (38.1 mm).
