    • A golf club has a lobe defining a first club head thickness spaced between leading and trailing edges of the club face and on an opposite side of the club head relative to the face. An entry region of the club head is located below the lobe and adjacent to the leading edge on an opposite side of the club head relative to the face, and is spaced inwardly from the lobe to define a second club-head thickness less than the first club-head thickness. The entry region permits the club head to penetrate downwardly into a ground surface. A curved transition surface extends between the lobe and the entry region, and cooperates with the lobe to guide the club head generally forwardly after downward penetration of the leading edge into the ground.
    • 高尔夫球杆具有一个凸缘,其限定了在球杆表面的前缘和后缘之间以及球杆头相对于面的相对侧间隔开的第一球杆头部厚度。 球杆头的入口区域位于叶片的下方并且相对于球杆头在杆头的相对侧上与前缘相邻,并且与叶片向内间隔开,以限定小于第一球杆头的第二杆头厚度 球杆头厚度。 进入区域允许球杆头向下穿入地面。 弯曲的过渡表面在凸起和入口区域之间延伸,并且与凸起协作以在向前穿过前缘进入地面之后大致向前引导球杆头。

    • A golf club head has a sweet spot defined by a central axis of the club face, and an elongated smooth surface extending in its elongated direction along at least a portion of the central axis and overlying the sweet spot. A first set of approximately parallel score lines are located on one side of the central axis, and a second set of approximately parallel score lines are located on an opposite side of the central axis. Each score line is oriented upwardly at an oblique angle relative to the central axis to impart spin about spin axes extending approximately in a direction of the score lines and at oblique angles relative to the central axis of the club face for correcting a direction of impact resulting from mishitting the ball toward the toe portion or the heel portion of the club face.
    • 高尔夫球杆头具有由球杆表面的中心轴线限定的甜点,以及细长的光滑表面,沿着中心轴线的至少一部分延伸到其细长方向并且覆盖该甜点。 第一组近似平行的刻痕线位于中心轴的一侧,并且第二组近似平行的刻痕线位于中心轴的相对侧上。 每个刻痕线相对于中心轴线以倾斜的角度向上取向,从而围绕围绕刻痕线的方向延伸的旋转轴线相对于球杆面的中心轴线以倾斜角度旋转,以便校正冲击方向 从球偏向球杆面的脚趾部分或脚跟部分。
