  • Putter head
    Patent number: 6905420
    Abstract: A putter (100) having a club head (20) having a central aperture (32) with a rearward center of gravity is disclosed herein. The club head (20) has a body (22) that is preferably composed of stainless steel. The body (22) has a face portion (24), a crown portion (26), a sole portion (28) and an aft-mass portion (30). The face portion (24), the crown portion (26), the sole portion (28) and the aft-mass portion (30) define the central aperture (32). The crown portion (26) extends rearward from the face portion (24) over the aft-mass portion (30). The central aperture (32) separates the crown portion (26) from the sole portion (28) and the face portion (24) from the aft-mass portion (30).
