Finally, a revolutionary technology that will change how you think about iron shafts. UST Mamiyas new Recoil Iron Shafts are a game changer. In the past, heavy weight graphite iron shafts felt dead and stiff. With UST Mamiyas exclusive Recoil technology, we have brought feel back into the shaft, while allowing players to hit a wide range of shots that result in better distance control and pin seeking accuracy.
