Abstract

A golf club head comprising a striking face section, a sole, and a flange extending about the periphery of the sole. The flange decreases in height from the upper edge of the striking face section to the back edge of the sole. A composition insert is secured within the front of the striking face section. This structure provides a crownless club head.
