Abstract
A geometric-shaped core for a golf ball has a plurality of outwardly extending projections formed on a spherical central portion thereof. A layer of a relatively less resilient material is applied in the interstitial space between the projections on the surface of the core, and a cover is applied over the core and interstitial layer. The geometric-shaped core is manufactured by first providing flexible, resilient, honeycombed inserts to be used in a conventional compression mold. The inserts are placed into the upper and lower mold cavities, the core material is added, and the geometric-shaped golf ball core is compression molded.
