The present invention is directed to a golf club head with an improved striking surface. The grooves are machined into the strike surface with tight tolerances. The grooves may contain a plurality of portions including a first portion that interfaces the striking surface with a variety of configurations.
Claims20
A golf club head, comprising:
- a generally planar striking face with a groove formed therein, wherein said groove contains:
- a first portion interacting with said face, wherein the first portion includes a radiused portion adjacent said face and the radiused portion defines a central angle θ;
- and
- a second portion adjacent said first portion, said second portion being defined by angled side walls that are angled by an angle A relative to a plane normal to said face and parallel to a longitudinal axis of said groove;
- wherein:
- θ+A<90°.
