{{Main|Foil (fencing)}}
The foil is a light thrusting weapon with a maximum weight of 500 grams. The foil targets the torso, 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 register on the electronic scoring apparatus (and do not halt the action). Touches that land outside the target area (called an ''off-target touch'' and signalled by a distinct color on the scoring apparatus) stop the action, but are not scored. Only a single touch can be awarded to either fencer at the end of a phrase. If both fencers land touches within 300 ms (± 25 ms tolerance)<ref>{{Cite web |title=Material rules |url=https://static.fie.org/uploads/32/163442-book%20m%20ang.pdf |access-date=2024-07-29 |website=FIE International Fencing Federation |page=82}}</ref> to register two lights on the machine, the [[referee]] uses the rules of "right of way" to determine which fencer is awarded the touch, or if an off-target hit has priority over a valid hit, in which case no touch is awarded. If the referee is unable to determine which fencer has right of way, no touch is awarded.
