The stabilizing surfaces of darts (flights) are designed to stabilize the darts in flight and enable accurate trajectory. If these stabilizing surfaces are damaged or bent, the geometry and aerodynamics are compromised, negatively impacting the dart's flight path. The invention achieves a rotating motion around the longitudinal axis of a dart in flight. This rotation creates a gyroscopic effect, which stabilizes the dart's trajectory. The rotation improves the dart's penetration into the target and reduces ricochets. The rotational movement allows the thrown darts to glide more smoothly past the darts already stuck on the dartboard. The rotational effect is achieved solely through deformation, without weakening the stabilizing surfaces with incisions or similar modifications. These deformations make the stabilizing surfaces stiffer, more dimensionally stable, and therefore more durable. The shape is created by bending the stabilizing surfaces (1) at the bending paths (2), thereby creating effective surfaces (3) that generate a rotational movement around the longitudinal axis during flight.
