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.
