5. A self-balancing golf putter comprising:
a club head having:
a clubface configured to make contact with a golf ball; and
a body on which the clubface is configured having:
a center of mass that is defined to be the point of intersection between an x-axis and a y-axis wherein the y-axis is parallel to the clubface and wherein the x-axis and the y-axis are in an x-y plane;
a lie angle radian defined to be through the center of mass, at an angle α1 from the x-axis and having a measurable distance greater than zero;
a lie angle axis that intersects the lie angle radian and is offset from and parallel to the x-axis; and
a radian plane parallel to the x-y plane; and
a shaft attached to the club head having a center axis, wherein the center axis converges with a balance point formed at an intersection of an end point of the lie angle radian and the lie angle axis wherein the center axis and the lie angle axis both lie in a lie angle plane and the lie angle plane and the radian plane form a lie angle α2 that is approximately equal to the angle α1 wherein the x-axis runs through the clubface at a negative x location on the x-axis and wherein the shaft is rearward leaning in a (−x, +y) quadrant of the x-y plane.
