Foil, épée, and sabre are the three weapons used in the sport of fencing. While it is not unusual for fencers to compete in all three events, they generally choose to develop their skills in one weapon. Until recently, women were permitted to compete only in foil, but now the world federation offers international competitions for women in épée and sabre. Women's épée was added to the World Championships in 1989 and was held for the first time at the Olympic Games in 1996. Women's sabre was only formally introduced in international competitions in 1999.

Foil and épée are point-thrusting weapons. Sabre is a point-thrusting as well as a cutting weapon. The target areas differ for the three weapons, though all three are scored electronically.

Foil

The foil, the modern version of the duelling rapier, has a flexible rectangular blade, approximately 35 inches in length, weighing less than one pound. Points are scored with the tip of the blade and must land within the torso of the body.

The valid target area in foil is the torso, from the shoulder to the groin, front and back. It does not include the arms, neck, head and legs. The foil fencer's uniform includes a metallic vest (called a lamé) which covers the valid target area, so that a valid touch will register on the scoring machine. A small, spring-loaded tip is attached to the point of the foil and is connected to a wire inside the blade. The fencer wears a body cord inside his uniform which connects the foil to a reel wire, connected to the scoring machine.

There are two scoring lights on the machine. One shows a green light when a fencer is hit, and one shows a red light when her opponent is hit. A touch landing outside the valid target area (that which is not covered by the lamé) is indicated by a white light. These "off-target" hits do not count in the scoring, but they do stop the fencing action temporarily.

Epée

The épée (pronounced "EPP-pay"), the descendent of the duelling sword, is similar in length to the foil, but is heavier, weighing approximately 27 ounces, with a larger guard (to protect the hand from a valid hit) and a much stiffer blade. Touches are scored only with the point of the blade. The entire body is the valid target area.

The épée is also an electrical weapon. The blade is wired with a spring-loaded tip at the end that completes an electrical circuit when it is depressed beyond a pressure of 750 rams. This causes the coloured bulb on the scoring machine to light up. Because the entire body is a valid target area, the épée fencer's uniform does not include a lamé.

Sabre

The sabre is the modern version of the slashing cavalry sword, and is similar in length and weight to the foil. The major difference is that the sabre is a point-thrusting weapon as well as a cutting weapon (use of the blade). The target area is from the bend of the hips (both front and back), to the top of the head, simulating the cavalry rider on a horse. The sabre fencer's uniform includes a metallic jacket (lamé), which covers the target area to register a valid touch on the scoring machine. The mask is different from foil and épée, with a metallic covering since the head is valid target area.

Just as in foil, there are two scoring lights on the machine. One shows a green light when a fencer is hit, and one shows a red light when the opponent is hit. Off-target hits do not register on the machine.
