The striking face (300) comprises a plurality of spaced, parallel grooves (332) that extend across at least a portion of the striking face. The grooves form a herringbone groove pattern. The herringbone groove pattern may include two or more rows of diagonal, parallel grooves slanting in alternate directions to form a series of parallel Vs. Also circular grooves (532) are disclosed. Other possible groove shapes also are described.</p> |
