The Odyssey Protype putters were designed with input from some of the world’s top players. The Protype line of putters are made from a soft 1025 carbon steel and feature a deep mill pattern on the face which provides better feel and a better roll of the ball. All models in the Protype line have specifically weighted heads for each shaft length. The Odyssey Protype 2-Ball putter is essentially the first milled, non insert version of the classic mallet design. The 2-ball allignment system aids golfers to get their putt started in the direction they intend.
