<p><P>PROBLEM TO BE SOLVED: To provide an iron-type golf club head incorporating one or more internal chambers provided in the top portion of a perimeter weighted iron club head. <P>SOLUTION: The golf club head has a face plate defining a striking face of the club head and a body having an annular mass disposed behind the striking face. The annular mass extends about a periphery of the face plate defining an external cavity centrally located on a rear side of the face plate. The annular mass includes a top portion extending along a top edge of the face plate, a toe portion extending along a toe edge of the face plate, a heel portion, and a bottom portion. At least one internal chamber is located adjacent to the top edge, as defined by the top portion of annular mass. The internal chamber, or a selected number of a plurality of internal chambers defined by the annular mass, can be filled to further manage the weight distribution of the club head. Thus the club head can be tuned to accommodate requirements of an individual gofer. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
