Abstract
Iron-type golf club heads are disclosed having a heel portion, a sole portion, a toe portion, a top-line portion, a front portion, a rear portion, and a striking face. The iron-type golf club heads include a localized stiffened region that is located on the striking face of the club head such that the localized stiffened region alters the launch conditions of golf balls struck by the club head in a way that wholly or partially compensates for, overcomes, or prevents the occurrence of a rightward deviation. In particular, the localized stiffened region is located on the striking face such that a golf ball struck under typical conditions will not impart a right-tending sidespin to the golf ball.
