Appendix II, 3(v) states that:
| A putter may have two grips provided that each is circular in crosssection, the axis of each coincides with the axis of the shaft, and they are separated by at least 1.5 inches (38.1mm).
If a putter were allowed to have two non-circular grips, it would be possible to mount the grips such that their cross-section would not be “generally similar” throughout the entire length (see Section 6-Cross-section). For this reason, putters which have two grips must have two circular grips and this is interpreted strictly such that the grips must not incorporate a reminder rib.
Where a putter has two grips, these grips will only be considered separate if the gap between them is at least 1.5 inches (38.1mm) in length. If a smaller gap exists, or if no gap exists, the total length from the bottom of the lower grip to the top of the upper one would be considered "one grip". Therefore, in both of the instances mentioned above, it is unlikely that the grip would conform if two conventional grips were used. Either the exposed piece of shaft between the two grips would constitute a waist, or the fact that two grips met in the middle would cause a bulge. The second example may be overcome if the lower grip is a continuation of the top grip, i.e. a continuation of the same taper and the transition between the two sections is a smooth one.
If a putter does have two grips, the upper grip must be at least 5 inches (127mm) in length. If the grip does not satisfy this requirement, it would be considered to be “moulded for the hands”.
It is worth emphasising that it is not permissible for wood or iron clubs to have more than one grip.
