Abstract: A golf putter head has a cylindrical body with a defined flat face on top, the body made up of an outer shell of an aluminum alloy and an inner core of brass. The head has a groove across the flat face of the top and at its center, with indicator material carried in the groove for alignment purposes. The head is sized so that the convex surface of the cylindrical body at its widest point will strike a golf ball at its corresponding widest point, thus providing for quick rolling action of the ball when putted. The combined outer shell/inner core structure is used to obtain favorable “feel” and balance properties.
