Abstract
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.

A putter comprising:
- a body comprising a face and a hosel;
- a dampening layer comprising a first front surface and a first rear surface;
- and
- a rear weight comprising a second front surface and a second rear surface,
- wherein the face comprises a striking surface and a third rear surface,
- wherein the dampening layer is affixed to the third rear surface,
- wherein the rear weight is affixed to the dampening layer,
- wherein the second front surface comprises a recess sized to receive a portion of the dampening layer,
- wherein a portion of the dampening layer is disposed within the recess, and
- wherein the first front surface is not parallel with the first rear surface.
