Abstract

A golf club head has a striking face with a plurality of scorelines including a first scoreline and a second scoreline adjacent thereto. The striking face also has a plurality of auxiliary grooves each spaced from the scorelines. In a first imaginary vertical plane, a first path is formed by a first intersection between the first imaginary vertical plane and the striking face, and the auxiliary grooves have a first concentration no less than 0.17 measured between the first and second scorelines. A second imaginary vertical plane is horizontally spaced from the first imaginary plane. A second path is formed in the second imaginary vertical plane by a second intersection between the second imaginary vertical plane and the striking face. The auxiliary grooves in the second imaginary vertical plane have a second concentration that is different from the first concentration measured between the first and second scorelines.
