Abstract
A golf club head is provided having enhanced flexibility for launching a golf ball and is most advantageous for use in a wedge-type golf club. An upper portion of the body of the golf club head has a reduced stiffness while a lower portion of the body has reduced stiffness recesses located toward the heel and 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, combines with a top to bottom difference in stiffness to provide enhanced flexibility and selectively increased stiffness for improved performance and feel.
