Abstract
A golf club is disclosed that has a golf club head with a face having peaks or ridges and deep grooves or valleys. The deep grooves or valleys promote improved “feel” and/or reduced “smash factor” which may be particularly desirable when the golf club head comprises a putter face. The deep grooves or valleys may eliminate the need for costly soft metal alloy faces and/or polymeric or other resilient inserts between the face and the body of the golf club head.

A putter head comprising:
- a heel, a toe opposite the heel, a sole, a top line opposite the sole, and a forwardly-facing striking face, the striking face including:
- a geometric center;
- a virtual elliptical region having a center coincident with the geometric center, a length dimension of 1.5 inches, and a height dimension of 0.75 inch;
- a first groove pattern comprising a plurality of arcuate first grooves, each of the arcuate first grooves having, in the virtual elliptical region of the striking face, a depth of 0.010-0.018 inch;
- and
- a second groove pattern that is substantially a mirror image of the first groove pattern overlaid onto the first groove pattern and comprising a plurality of arcuate second grooves that have, in the virtual elliptical region, a depth substantially the same as that of the arcuate first grooves,
- wherein each groove of the arcuate first grooves and the arcuate second grooves comprises an arc of a circle, and the arcuate first and second grooves fatal, at intersecting regions, four-sided ridges that decrease in area from a lowermost region of the virtual elliptical region to an uppermost region of the virtual elliptical region.
