Fencing is a group of three related combat sports. The three disciplines in modern fencing are the foil, the épée, and the sabre; winning points are made through the weapon's contact with an opponent.

Competitors win by being the first to score 15 points (in direct elimination play) or 5 points (in preliminary pool play) against their opponent, or by having a higher score than their opponent when the time limit expires. The points are earned by contacting the opponent with the blade. The movement is so fast the touches are scored electrically. Each discipline has different swords and different rules.

A fencer is the only role for the sport.

The main requirements to fence is to use fencing blades. The three different types of blades are Epee, Foil, and Saber. It's also required to wear fencing clothes and protection that prevent any risk of injury from the blades.

The foil sword: The foil has a maximum weight of 500 grams and is a thrusting weapon. Only the tip of the blade counts with the target area the torso which is covered by the lamé.
The épée sword: The épée is also a thrusting weapon but has a maximum weight of 775 grams. Again, only the tip of the blade counts but the target area is the entire body so there is no lamé.
The sabre sword: The sabre is a cutting and thrusting weapon with a maximum weight of 500 grams. The entire blade can score with the target area the upper half of the body, covered by the lamé, including the face mask and neck bib which must also be made of conducting material.

Aladár was a Hungarian fencer, regarded as "The greatest Olympic swordsman ever". He won seven gold medals in sabre at six different Olympic Games.
