The "horn blade" as it has come to be known is a device affixed to the helmets of open cockpit unicorn racing drivers everywhere. It features an aerodynamic "blade" shrouding the horn completely to protect it from the high velocity air flow as well as debris. It is mounted to the helmet on a reinforced base, with the upper portion attached to a swivel, allowing it to pivot into the incoming air stream preventing any adverse forces being applied to the horn as well as significantly reducing turbulence and flow separation compared to traditional horn shrouds thanks to it's aerodynamic shape.
