In fencing, the three main weapons used are the foil, the épée, and the sabre. Each weapon has distinct rules and target areas. The foil is a lightweight weapon focusing on point technique and requires touches on the torso. The épée is heavier and allows hits anywhere on the body. The sabre is a cutting weapon targeting the upper body, and it has a unique scoring system that combines both cutting and thrusting. Fencing emphasizes agility, precision, and strategy, making it a unique and thrilling sport.
