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.
Claims41
A putter-type golf club comprising:
- a shaft having a grip at a proximal end of the shaft, and a putter head attached to a distal end of the shaft;
- the putter head further 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 first groove pattern comprising a plurality of arcuate first grooves, each of the arcuate first grooves having, in a preferred hitting zone of the striking face, a depth of 0.010-0.018 inches and a width, as measured along a line perpendicular to a tangent of each of the arcuate first grooves, of 0.004-0.008 inches.
A golf putter having a head with a putter face comprising a plurality of grooves having a depth of 0.010-0.018 inches and exhibiting an average smash factor, upon striking a golf ball, of less than 1.6.
A putter-type golf club head having a top line, a sole, a heel, a toe, and a face, the face having a plurality of peaks and valleys therein, the valleys having a depth of 0.012-0.018 inches.
A putter-type golf club head having a top line, a sole, a heel, a toe, and a face, the face having a plurality of grooves therein, wherein the plurality of grooves comprise:
- first grooves having a first depth and located in a first region proximate the toe;
- second grooves having a second depth and located in a second region proximate the heel;
- and third grooves having a third depth and located in a third region comprising a central hitting zone of the face, wherein the first depth and second depth are different from the third depth.
A golf club head having a top line, a sole, a heel, a toe, and a face, the face having a plurality of grooves therein, wherein the plurality of grooves transition in groove depth from a shallower depth in a first region of the face proximate the toe, to a deeper depth in a second region proximate a hitting zone of the face, to a shallower depth in a third region of the face proximate the heel.
