Abstract: A putter has a body member that has a top surface and a bottom surface joined by a first face, a second face disposed at an obtuse angle relative to the first face, a third face, a fourth face disposed at an acute angle relative to the third face, and a fifth face disposed at an obtuse angle relative to the first face. A groove system runs from the second face through to the fifth face via the third face and the fourth face. A plurality of azimuth lines radiate outwardly from the connection point of the third face and the fourth face toward one of the first face, the second face, or the fifth face. A shaft is attached to the top surface of the body member.
