Abstract

An iron-type golf club head includes a striking face; a base surface opposite the striking face; and a perimeter weighting element surrounding the base surface and including a top-line portion, a sole portion, a heel portion, and a toe portion. A first auxiliary cavity is delimited by the perimeter weighting element and a first perimeter wall, the first perimeter wall coupled to the sole portion and to the heel portion of the perimeter weighting element. A second auxiliary cavity is delimited by the perimeter weighting element and a second perimeter wall, the second perimeter wall coupled to the sole portion and to the toe portion of the perimeter weighting element. A central cavity is at least partially delimited by the base surface, the perimeter weighting element, the first perimeter wall, and the second perimeter wall, and an insert is within the central cavity.
