  • Patent number: 5863262
    Abstract: A golf putter head having a continuous face comprised of a curved section leading into a hemi-toroid section with an increasingly flattened surface progressively leading into a negative angle of from about 2.degree. to 10.degree. from a vertical face. The head is configured to present the curved section relative to a golf ball when the head is positioned below an equator of the ball, and to present a flattened surface at each angle that the putter head contacts the ball. Accidental hop is prevented and the ball is struck true at every incident point of contact between the putter head and the ball.
