These striking Carbon Dart Shafts in the Shot Koi range are designed for World Champion Michael Smith, with a stunning red color applied, and the St Helens V Design. Koi dart stems have a two-pointed taper to ensure the shaft is durable where it needs to be, right up to the point where it meets the dart flight. Multiple filets work together at the tip to help locate the flight while reducing deflection and limiting breakages. Chamfered cuts at an optimal depth ensure dart flights fit securely and sit flush inside the dart shaft. Koi shafts are crafted from tough carbon composite for strength.
