Abstract:
A golf club head including a planar face with a pattern of horizontal grooves therein, each of said grooves defining an opening in the planar face and including a first side, a second side, a pair of top junctures where said first and second sides join said planar face, a bottom, and a pair of bottom junctures where said first and second sides join said bottom, a spacing distance between said first and second sides continuously increasing from said bottom junctures to said top junctures, said first side being substantially a mirror image of said second side, each of said sides having a lower section positioned adjacent to said bottom and an upper section positioned adjacent to said face, each of said lower and upper sections being substantially planar, an angle formed by planes that are co-planar with said upper sections and extending downward therefrom having a measurement greater than an angle formed by planes that are co-planar with said lower sections and extending downward therefrom, each of said top junctures being concavely rounded, each of said bottom junctures being concavely rounded, a middle juncture being defined between each of a pair of adjacently positioned upper and lower sections, each of said middle junctures being convexly rounded.
