A putter head comprising a novel alignment structure is disclosed herein. In particular, the putter comprises an alignment sphere attached to an upper surface of a lower flange and an alignment ring suspended over the lower flange and vertically aligned with the alignment sphere. When a golfer has oriented the putter properly in front of a golf ball at address, the alignment sphere will appear to the golfer to be encircled by the alignment ring.

Putter Head

A golf club putter having a low head center of gravity and a high MOI is disclosed herein. The putter has a metal body comprising a face and a hosel, a low density dampening layer affixed to the body, and a high density rear weight affixed to the dampening layer, and the dampening layer has a first surface that forms an angle with an opposing second surface that is inversely proportional to the distance of the hosel from a heel side of the body.

Multiple material putter

A golf club putter having an alignment pattern is disclosed herein. The alignment pattern has first and second long lines that approach each other as they extend from an aft region of the putter to a front region of the putter and, when the putter is properly aligned with a golf ball, create an optical illusion of convergence of said lines at or near a center of the golf ball without actually intersecting.
