The club head is molded or formed in substantially one piece, the crown having an opening which is sealed by securing a crown plate in the opening. The metal wood has a nonmetallic insert secured to a cavity formed in the ball striking face and reinforced by ribs on the interior of the face and the walls of a cavity formed in the club striking face. The insert is secured in the cavity by adhesion which is enhanced by channels formed in the insert cavity and hollow columns formed in the insert. |
