US Patent 7144331 Metal wood

A substantially hollow body metal wood golf club head has a wrap around insert that comprises a substantial portion of the front face. The insert having a wing-like extension that extends around the heel portion of the club head and a pre-determined distance of about 0.657 inch into the skirt portion of the club head. A gap of about 0.06 inch to about 0.36 inch is created between an internal thru-hosel and the interior wall of the heel. The gap represents material and weight that may be used more effectively in other parts of the club head. The lack of connection between the hosel and the front face creates a greater unsupported front face and therefore a greater “sweet spot” area.
