Abstract
A wood type golf clubhead includes a face, a sole, a crown, a toe portion, a heel portion, and a hosel portion adjacent the heel portion. The hosel portion has an inverted or recessed portion which includes a generally concave wall. A hosel tube extends upwardly from the hosel portion. The hosel tube is supported within a boss which is formed integrally with the inside surface of the face. An alignment groove is provided at the intersection between the face and the crown, and the groove includes a surface which lies within a plane which is substantially vertical when the clubhead is soled at address. The sole includes a flat portion for supporting the clubhead at address, and a rear wall curves upwardly and rearwardly from the flat portion to the crown. The toe portion and the crown merge at a relatively sharp angle to provide a streamlined shape.
