  • Publication number: 20030008724
    Abstract: A golf putter including a head attached rigidly to a shaft through the center of mass to minimize lateral rotation and to promote a pendulum like stroke, having optimized mass and shape to create a powerful “sweet spot” enabling consistent distance control, superior “feel” and increased “touch” while providing tangible “forgiveness” for random changes in dynamics introduced by less skilled players; the head having a continuous face comprised of a non-radial contour to provide improved rebound trajectory by initiating overspin and minimizing outside effects on the ball until all gyroscopic properties allow it to become a stabilized mass. The head includes a narrow sole to decrease drag, a doze to brush back taller grass, increasing the odds of making putts launched from less manicured greens or fringe areas, and semi circular markings approximating the radius of a golf ball to enable alignment of the ball with the “sweet spot”.
