    • 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.
    • 高尔夫球杆头具有带有多个刻痕线的醒目面,包括与其相邻的第一刻痕线和第二刻痕线。 打击面还具有多个辅助凹槽,每个辅助凹槽与刻痕线间隔开。 在第一假想垂直平面中,第一路径由第一假想垂直平面和撞击面之间的第一交点形成,并且辅助槽具有在第一和第二记分线之间测量的第一浓度不小于0.17。 第二假想垂直平面与第一假想平面水平间隔开。 通过第二假想垂直平面和打击面之间的第二交叉点在第二假想垂直平面中形成第二路径。 第二假想垂直平面中的辅助槽具有不同于在第一和第二记分线之间测量的第一浓度的第二浓度。

    • A golf club head includes a striking face having a face center, a bottom portion, a top portion including an exterior surface, a hosel including an imaginary vertical hosel plane, a forwardmost point, and a rearwardmost point. In an imaginary vertical plane perpendicular to the hosel plane and passing through the face center, the exterior surface includes a path having a first point and a second point rearward of the first point. An imaginary infinite straight line passes through the first point and the second point, but does not penetrate the exterior surface. A segment of the imaginary straight line is delimited by the first point and the second point. A maximum distance between the segment and the exterior surface of the top portion is no greater than 0.70 mm and a distance between the first point and the second point is no less than 22 mm.
    • 高尔夫球杆头包括具有面中心,底部部分,包括外表面的顶部部分的击打面,包括虚拟垂直插鞘平面的插鞘,最前端点和最后点。 在垂直于插鞘平面并穿过面部中心的假想垂直平面中,外表面包括具有第一点和第二点后面的第一点的路径。 假想无限直线穿过第一点和第二点,但不穿透外表面。 假想直线的一段由第一点和第二点界定。 该顶部与该外表面之间的最大距离不大于0.70mm,第一点与第二点之间的距离不小于22mm。
