Abstract

A putter-type golf club head has a top portion, a bottom portion, a heel portion, a toe portion, and a striking face having a variably textured region. The variably textured region includes a central portion and an outer portion laterally spaced from the central portion towards one of the heel portion and the toe portion. The central portion has a material ratio of less than 20% at a cutoff height of 0.1 mm and the outer portion has a material ratio greater than that of the central portion at the cutoff height of 0.1 mm. Variation of the textured region provides consistent ball speed upon impact at different lateral positions of the striking face.
