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.

Claim (Index 8):
A clubhead for an iron-type golf club comprising:\n a heel, a toe, a sole, a top-line of the iron-type golf club clubhead, a striking face having a forward-facing ball-striking surface, a rearward-facing surface, and an ideal striking location; and a perimeter weight surrounding the striking face; wherein the striking face has a supported region supported by the perimeter weight and an unsupported region, with the ideal striking location lying within the unsupported region, the unsupported region having a thickness that varies in a heel-toe direction; wherein a heel portion of the unsupported region of the striking face is located on a heel side of an imaginary center vertical plane that extends perpendicularly to the ground plane and that contains an imaginary line that extends in a direction normal to the striking face at the ideal striking location when the clubhead is in the normal address position, and wherein a toe portion of the unsupported region of the face is located on a toe side of the imaginary plane; wherein a hitting region of the unsupported region of the striking face lies between an imaginary heel side vertical plane and an imaginary toe side vertical plane, where the heel side vertical plane is spaced 20 mm to the heel side and is parallel to the center vertical plane, and the toe side vertical plane is spaced 20 mm to the toe side and is parallel to the center vertical plane; wherein the clubhead has a relative coefficient of restitution of at least \u22120.030; and wherein the following two inequalities are satisfied:\n SA TOE >SA HEEL ,\u2003\u2003(1) \n and \n [(\u03a3 n=1 N E n t n 3 )\u00f7 N ]\u00f7[(\u03a3 m=1 M E m t m 3 )\u00f7 M]> 1.4;\u2003\u2003(2) \n wherein: SA TOE HR  is defined as the surface area of the toe portion of the hitting region, SA HEEL HR  is defined as the surface area of the heel portion of the hitting region, E n  and t n  are the effective Young's Modulus value and the thickness, respectively, for the n th  cross-section of the toe portion of the hitting region of the striking face, E m  and t m  are the effective Young's Modulus value and the thickness, respectively, for the m th  cross-section of the heel portion of the hitting region of the striking face, and N and M have values determined by discretizing SA TOE HR  and SA HEEL HR , respectively, into 1 mm\u00d71 mm sections.
