Foil (fencing)

A foil is a specialized, flexible weapon used in the sport of fencing. It is the most common weapon used in modern competitive matches. The weapon features a rectangular cross-section and a blunt tip. Unlike a real sword, the foil is designed for safety and precision. Points are only scored by making contact with the tip. This means fencers must use quick, accurate thrusts rather than slashes.

Modern foils come in two main varieties: electric and non-electric. Non-electric foils are often called "steam" or "dry" foils. They are primarily used for practice sessions. In these matches, a judge must manually watch to determine who scores. However, most international organizations require electric scoring. Electric foils use a specialized button assembly at the tip. This assembly includes a barrel, plunger, spring, and retaining screws.

When using an electric foil, the weapon acts as part of a circuit. The tip is part of a "normally closed" circuit. This means the power flows constantly while the tip is at rest. When the fencer depresses the tip against an opponent, the circuit breaks. This action signals the scoring apparatus to light up. To ensure a valid hit, the tip must stay depressed for at least 15 milliseconds. The force of the hit must also be at least 500 grams.

The scoring system relies on a metallic vest called a lamé. This vest is worn over the torso to define the valid target area.

When the tip hits the lamé, the machine registers a valid touch. The machine uses color-coding to show the results. Red or green lights indicate a valid hit on the target. White or yellow lights indicate an off-target hit. An off-target hit stops play but does not award a point.

Fencers hold their weapons using different types of grips. Most competitive athletes use a pistol grip. This design is ergonomic and fits the hand into a specific position. The pistol grip offers a wider range of handling than other styles. Some fencers still use the Italian grip, which is legal in modern competition. The French grip is also an option, though it is used rarely. The blade is held together by a tang that extends into the grip. A pommel acts as a fastener to secure the entire assembly.

The history of the foil is tied to the evolution of swordsmanship. It began as a training tool for the small-sword used in the 18th century.

In France, it helped fencers practice elegant, fast thrusting. The modern target area is based on old dueling traditions. Because duels were often fought to the death, fencers aimed for the torso. This area contains the vital organs. Foil was included in the first Olympic Games in 1896. Women's foil was introduced at the 1924 Paris Olympics.

Fencing matches are governed by a system called priority, or "right of way." This rule helps referees decide who receives a point during an engagement. If both fencers hit at the same time, priority determines the winner. The referee identifies who the attacking fencer is to assign priority. A defender can take priority by performing a parry. A parry is when the defender deflects the attack using the strong part of their blade.

Priority can also change if an attack misses its target. A defender can also gain priority by "beating" the opponent's blade. This involves striking the weak part of the opponent's blade with your own. The sport is organized into many age groups to ensure fair competition. These include Y10, Y12, Y14, cadet, junior, and senior levels. This structure allows athletes to develop their skills safely as they grow.
