Dominant arm: Left (Lefty) Odyssey TRI-BALL SRT This is an Odyssey TRI-BALL SRT for left-handed players, rarely seen in the used market. The grip was worn out, so I cleaned it up by removing the worn parts and then applied heat shrink tubing. I think I did a good job. This model's concept is to generate approximately 2.5 times the moment of inertia of a regular "2-ball" by attaching a high-density metal frame to the three ball-shaped alignment aids (TRI-BALL). The TRI-BALL SRT is the putter that professional Shingo Katayama used to win the first domestic senior tournament. Because of the three balls lined up, it's commonly called the "3-ball," and it's a putter that gained attention for its large projected area, making it easier to hit than the "2-ball."
