US Patent 7297072 Composite metal wood club

A metal wood golf club head adapted for attachment to a shaft, comprising of a body portion and a crown portion, each portion constructed of a different density material. Combining a high-density material in the body portion, with a low-density material in the crown portion, creates an ultra-low center of gravity relative to the geometric face center, resulting in higher launch angles and spin rate ratios. The material for the crown portion is preferably a composite. A vibration dampening gasket is disposed between the ledge and lip sections of the body and crown respectively.
