Fencing
There are three types of fencing - epee, foils and sabre.
An Overview of Fencing
In all three, weapons are wired electronically to record when a hit is scored. In foils and epee, points can only be scored by the point of the weapon hitting. In the case of the foil, only a hit on the torso counts. In the epee, the whole body is the target. In sabre, points can also be scored by hitting the arms and head.
