Abstract

A golf putter includes a putter head which utilizes a weight management system to allow for an infinite variation in putter sweet spot adjustment. In one embodiment, the putter head combines a flat putting surface with a cylindrical bore which receives the weight management system. Alternatively, a cylindrical putter head is provided which has a diameter matching the diameter of a golf ball. The cylindrical putter head can also have a threaded interior bore for receipt of the weight management system.

Claims

1. A putter comprising

a) a shaft;

b) a putter head attached to one end of the shaft, said putter head having a flat putting surface and a sweet spot adjuster integrally formed with said putter head, said sweet spot adjuster comprising a cylindrical threaded bore extending through a portion of said putter head and being aligned parallel to said flat putting surface and a unitary threaded weight assembly sized to be threaded into said cylindrical threaded bore, said cylindrical threaded bore positioned in said putter head so that an axis of said shaft where said shaft meets said putter head intersects said cylindrical threaded bore, said unitary threaded weight assembly being movable along an axis of said cylindrical threaded bore to fine tune the location of a sweet spot in said putter head and further comprising a slotted and threaded plug having a threaded leg extending from one side thereof, at least one annular weight mounted on said threaded leg and a fastener securing said annular weight to said threaded plug.

2. The putter of claim 1 wherein the outer diameter of the plug matches an inner diameter of the cylindrical threaded bore.
