Abstract: The invention presented herein is directed to a back cavity insert for a cavity-backed iron-type golf club head. The rear perimeter of the iron-type golf club head and the rear surface of a strikeface cooperate to define a back cavity. The rear perimeter can comprise any edge or percentage of the perimeter of the back cavity. An insert may be placed into the back cavity such that the insert covers at least 60 percent to 100 percent of the strikeface rear surface area. When the insert is attached to the iron-type golf club head strikeface rear surface, it will interact with the iron-type golf club head strikeface when the strikeface deforms and rebounds. The insert thickness, composition, and stiffened outer surface may unduly restrain the deformation or flexing of the strikeface and reduce the amount of energy returned to the golf ball.

Abstract: Embodiments of an iron-type golf club head comprising a high moment of inertia and a damping system. The damping system includes an insert covering a lower portion of the back face and a badge covering an upper portion of the back face. The damping system covers a large proportion of the back face and provides a club head with desirable sound and feel characteristics.
