The Heavy Putter Model A3 is a blade head design with a double bend shaft. The head weighs 475 grams (including the pre-installed stainless steel tip weights). There is a 250 gram counter balance weight in the grip end of the shaft that creates a balance point 75% higher up the shaft than a conventional putter. The tip weight kit (included) raises or lowers the head weight by 25 grams (up to 500g or down to 450g).
MATTE vs TOUR
The Tour model A3 is 100% CNC milled from a single block of billet steel which creates an extremely precise putter in dimension as well as the molecular alignment within the metal. The Matte A3 is made like most putters on the market (cast metal) and then the face of the putter was CNC milled to provide better control over the ball.
The average player will not feel a difference between these two putters as the tour model was specifically made for the more distinguished players.
