Abstract

A golf club head with improved striking face is disclosed. For example, the golf club head may include a body portion, including a pocket, and a striking face portion. The pocket may include a perimeter ledge receiving a gasket bonded thereon. The golf club head may include a face insert bonded to the body portion via the gasket. The face insert may include a thickened central region having a first thickness. The perimeter ledge, gasket, and perimeter of the face insert may combine to create a thickened stress reducing region with a second thickness greater than the first thickness.

Claims
