ABSTRACT:
A steering element for a blade which is preferably mounted with respect to or part of an arrowhead or broadhead. During flight, a leading surface of the steering element contacts with airflow. One or more force components act in a direction generally perpendicular to a flat surface of the blade, to impart rotation or spin of a body of the arrowhead about a longitudinal axis of the arrowhead.
