摘要:
A putter-type club head (20) having a body (22) and a peripheral mass belt (23) is disclosed herein. The putter-type club head (20) has a body (22) that is preferably composed of an aluminum alloy. The body (22) preferably has a face portion (24), a crown portion (26), a sole portion (28) and a column portion (30). The face portion (24), the crown portion (26), the sole portion (28) and the peripheral mass belt (23) define a central aperture (32). The crown portion (26) extends rearward from the face portion (24). The central aperture (32) separates the crown portion (26) from the sole portion (28) and the face portion (24) from the central mass portion (80). The crown portion (26) preferably has an alignment means (40) thereon for aiming a golf ball during putting which preferably comprises three circular inserts (40a-c).

摘要:
A golf club head made of a ferrous metal and having a density in the range from about 5 to about 6.8 g/cm3 and from about 7.0 to about 7.4 g/cm3, and such heads made of a cast ferrous metal having a density in the range from about 5 to about 7.4 g/cm3. The entire golf club head may be made of such ferrous metal. Or, the ferrous metal is preferably a ductile iron or gray iron. The ferrous metal may be present as an insert in the ball hitting face of the club head, and the body of the club head may be a material different from the ferrous material. Or, the body of the club head may be made of the ferrous metal and the ball hitting face of the club head may be a different material.

摘要:
An iron-type golf club head having a sole, a center of gravity CG, and a static contact point SCP on the sole substantially vertically below the CG for providing stability when the club head is in an address position, but the sole has no points lower than the SCP when the club head is in the address position. Additionally, the club head may have a centerline plane orthogonal to the plane of the club face and containing the centerline of the club face, with the center of gravity lying in the centerline plane and the lowest point LP on the sole also lying substantially in the centerline plane when the centerline plane is substantially vertical, for minimizing mis-hits with the club head.
