There are three types of fencing - epee, foils and sabre.
In all three, weapons are wired electronically to record when a hit is scored.
With the epee, points can only be scored by the point of the weapon hitting. The epee is the heaviest of all weapons and has a stiffer blade than the others.
The blade is also V-shaped in cross-section and has a larger bell guard.
The technique varies with the other two, with there being no rules regarding priority and right-of-way.
Regarding the scoring, the entire body area is a valid target area.
