ABSTRACT:
An improved golf putter comprising a shaft, a generally resilient tubular or cylinder shaped main body member and a pair of unitary solid weight members each one being releasably attachable to one end of the main body member. The main body member includes end walls at each end thereof and a threaded opening formed within each of the end walls. Each weight member has an outer diameter substantially the same as the exterior diameter of the main body member and a threaded rod integrally formed therewith for threaded engagement with the threaded opening in each of the end walls. The end of each of the weight members that is opposite the end with the threaded rod is usually rounded. The end walls and their corresponding weight members are secured in abutting relation. Generally, the density of the material comprising the weight member is greater than the density of the material comprising the main body member and the combined weight and length of the weight members is greater than the weight and length of the main body member, respectively. The weight members are interchangeable with members having different densities, weights and lengths.
