Claims19
A golf club head comprising:
- a toe end;
- a heel end opposite the toe end;
- a top rail;
- a sole opposite the top rail;
- a recess positioned on a front surface of the golf club head;
- and
- a face insert positioned within the recess;
- wherein
- the face insert comprises:
- a face insert base;
- and
- a ball striking face plate having a front striking surface and a rear surface, wherein the rear surface is positioned adjacent to a front surface of the face insert base;
- and
- the ball striking face plate covers greater than 91% of the front surface of the face insert base;
- wherein the face insert is positioned within the recess using tape, glue, or epoxy;
- and
- a plurality of grooves disposed on the ball striking face plate between the top rail and the sole, each groove of the plurality of grooves extending between the toe end and the heel end;
- wherein
- the depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end;
- and
- the deepest portion of at least one groove is defined by a generally planar bottom surface portion of the groove.
