Abstract:

A golf putter head is provided that includes a base element, the base element including a golf ball striking surface, at least one alignment rail, a lip, the lip extending the entire front width of the golf putter head and a top surface, the top surface located at the rear of the golf putter head, an upper plate the upper plate configured to be secured to the base element at the lip and the top surface, the upper plate includes at least one aperature and the upper plate completely covering the top surface. The upper plate further includes at least one indicator marking, the at least one indicator marking configured to align with the at least one alignment rail and the aperature is sized such that the at least one alignment rail may be viewed through the aperature. The mass of the putter head is distributed such that the mass of the upper plate is greater than the mass of the base element, thereby positioning the center of gravity of the putter head above a centerline of the golf ball striking surface and an equator of a golf ball when the golf ball is positioned proximate the golf ball striking surface of the golf putter head.
