Patent ID: 8808108

Claim:
An apparatus comprising: a golf club head body comprising: a heel; a toe opposite the heel; a strike face comprising a leading edge; a rear opposite the strike face; and a hosel comprising a hosel axis and located at the heel and approximately at or in front of the leading edge; wherein: a toe-heel distance is equal to a distance between a first point at the toe and a second point at the heel; a front-rear distance is equal to a distance between a third point at the strike face and a fourth point at the rear; the golf club head body comprises: a first ratio of a moment of inertia of the golf club head body versus a mass of the golf club head body greater than approximately 12 cm 2 when a density of the golf club head body is equal to a first density, the toe-heel distance is equal to a first toe-heel distance, and the front-rear distance is equal to a first front-rear distance; a second ratio of the moment of inertia versus a volume of the golf club head body greater than approximately 25 g/cm when the density of the golf club head body is equal to the first density, the toe-heel distance is equal to the first toe-heel distance, and the front-rear distance is equal to the first front-rear distance; and a third ratio of a first distance versus a second distance greater than approximately 0.7; the first distance is measured as a shortest distance between a first plane intersecting the hosel axis and a center of gravity of the golf club head body; the second distance is measured as a shortest distance between a second plane intersecting the leading edge of the strike face and the center of gravity; the first and second planes are perpendicular to a third plane representing a ground surface when the golf club head body is at an address position and when the density of the golf club head body is equal to the first density, the toe-heel distance is equal to the first toe-heel distance, and the front-rear distance is equal to the first front-rear distance; and the volume of the golf club head body is between 60 cm 3 and 150 cm 3 .
