Abstract
A set of iron golf clubs is disclosed, each golf club having a head configured to provide enhanced flexibility for launching a golf ball. An upper portion of the body of each head has a reduced stiffness, while a lower portion of the body is configured with recesses that provide reduced stiffness toward the heel and the toe. A low central region supports the head at impact with the golf ball. The relative stiffness in the lower portion of the club head, varying from heel to toe, is designed in conjunction with a top to bottom difference in stiffness. Thus, the golf club head has enhanced flexibility and selectively increased stiffness, for improved performance and feel.
