    • Putters include a putter body having a ball striking face member made of a material having a first hardness characteristic. A cavity is defined in the putter body behind the ball striking face member, and plural openings are defined in the ball striking face member extending rearward with respect to the ball striking face member and into the cavity. A polymeric material at least partially fills the openings and the cavity, wherein the polymeric material has a second hardness characteristic that is softer than the first hardness characteristic. The ball striking face member and the polymeric material exposed in at least some of the openings provide a ball striking surface of the putter. The ball striking surface may include grooves or scorelines to affect the launch angle, spin, and/or roll of the ball during a putt. Methods for making such putter devices also are described.
    • 推杆包括具有由具有第一硬度特性的材料制成的打击面构件的推杆主体。 在击球面构件后面的推杆主体中限定空腔,并且在相对于击球面构件向后延伸并进入空腔的击球面构件中限定多个开口。 聚合物材料至少部分地填充开口和空腔,其中聚合物材料具有比第一硬度特性软的第二硬度特性。 暴击在至少一些开口处的击球面构件和聚合材料提供了推杆的击球面。 击球表面可以包括凹槽或刻痕线,以在推杆期间影响球的发射角,旋转和/或滚动。 还描述了制造这种推杆装置的方法。
