Very similar to the Gripper range but with flashes set into the shaft finish. Like the gripper the Catalyst represents great value for money due to the resilience of these shafts. All catalyst shafts are moulded and feature a ring grip top. The ring grip works in two ways. 1. It clamps the top fingers closed and maintains a good grip on the flight ensuring that it does'nt come lose mid flight. 2. It helps defend the flight grips against dart on dart collisions.
