Abstract
A golf club head having selectively oriented zones of relatively high flexural stiffness is disclosed. The hitting face is configured and dimensioned so that it includes an inner zone and a concentric intermediate zone. The inner zone has relatively high flexural stiffness and the intermediate zone has relatively lower flexural stiffness. The inner zone may have an elliptical shape or a substantially parallelogram shape. Preferably, the inner zone has a shape that comprises a major axis and a minor axis and the major axis aligns substantially in the direction of high heel to low toe. This arrangement of inner and intermediate zones creates a gradient of flexural stiffness in the direction of high toe to low heel and produces a desirable manipulation COR in that direction.
