In which style of fencing is the entire body a valid target zone?

In epee fencing, the entire body is considered a valid target zone. This means that a competitor can score points by hitting any part of their opponent's body, including the head, arms, torso, and legs. This characteristic differentiates epee from other styles, such as foil and sabre, where only specific target areas are valid for scoring.

In foil fencing, only the torso, including the area of the front and back, is a legal target, while the arms, head, and legs are not valid target zones. In sabre, the target area includes everything above the waist, but not the legs or feet. This makes epee the only style in which any and every part of the opponent can be struck to score points, leading to a unique strategy and approach in matches.
