Putters include a putter body (200) having a ball striking face member (204) made of a material having a first hardness characteristic. A cavity (208) is defined in the putter body behind the ball striking face member, and plural openings (206) 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 (204b) 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.

L'invention porte sur des putters qui comprennent un corps de putter (200) ayant un élément (204) à face frappant la balle, fait d'un matériau ayant une première caractéristique de dureté. Une cavité (208) est définie dans le corps de putter, derrière l'élément à face frappant la balle, et plusieurs ouvertures (206) sont définies dans l'élément à face frappant la balle, lesquelles ouvertures (206) s'étendent vers l'arrière par rapport à l'élément à face frappant la balle et à l'intérieur de la cavité. Un matériau polymère (204b) remplit au moins partiellement les ouvertures et la cavité, le matériau polymère ayant une seconde caractéristique de dureté qui est plus molle que la première caractéristique de dureté. L'élément à face frappant la balle et le matériau polymère exposé dans au moins certaines des ouvertures fournissent une surface de frappe de balle du putter. La surface de frappe de balle peut comprendre des rainures ou des pliures pour affecter l'angle de lancement, l'effet de balle et/ou le roulement de la balle durant un putt. L'invention porte également sur des procédés de fabrication de tels dispositifs de putter.
