Abstract
A golf club head is provided, including a planar face with a pattern of horizontal grooves therein each having a cross section with an opening in the planar face. The grooves each include a first side, a second side, a pair of top junctures where the first and second sides join the planar face, a bottom and a pair of bottom junctures where the first and second sides join the bottom. The spacing between the first and second sides continually increases from the bottom to the top junctures. Each of the sides includes a lower section positioned nearer the bottom and an upper section positioned nearer the face. Each of the lower and upper sections is substantially planar. The top junctures are convexly rounded and the bottom junctures are concavely rounded.
