There are three types of fencing - epee, foils and sabre.
In all three, weapons are wired electronically to record when a hit is scored.
The main difference with the sabre is that you can score with the edge of the blade.
As a result, movements with the sabre and the ensuing attacks are very fast.
As with the foil, sabre uses the convention of right-of-way to determine who acquires the touch.
The target area is from the waist up, but excludes the hands.
