Foil: a light thrusting weapon that targets the torso (including the back), neck, and groin, but not the arms or legs. The foil has a small circular hand guard that serves to protect the hand from direct stabs. As the hand is not a valid target in foil, this is primarily for safety. Touches are scored only with the tip; hits with the side of the blade do not count, and do not halt the action. Touches that land outside of the target area (called an off-target touch) stop the action, but are not scored. Only a single touch can be scored by either fencer at one time. If both fencers land valid touches at the same time, the referee uses the rules of “right of way” to determine which fencer gets the point. If both fencers begin their attack at the same time, or the referee is unable to determine who was first, neither fencer scores a point.
