    • A face insert comprising a planar member composed of a rigid material such as plastic or metal and a polymeric backing is disclosed herein. The planar member, which makes contact with a golf ball during use, includes a plurality of geometrically-shaped holes, each of which comprises a perimeter edge that has a variable radius to further optimize performance of the face insert. In some embodiments, one or more of the holes extends completely through the planar member, i.e. is a through-hole, and the polymeric backing includes at least one protrusion with an angled upper surface that is sized to extend into a through-hole and further improve performance of the face insert. The face insert described herein can be used with any type of golf club head, including putters, woods, irons, and hybrids, and the holes may take any shape, including oval, hexagonal, and chevron.
