The sabre is one of the three weapons of modern sport fencing, and is alternatively spelled saber in American English. The sabre differs from the other modern fencing weapons, the épée and foil, in that it is possible to score with the edge of the blade; for this reason, sabreur movements and attacks are very fast. For the other two weapons, valid touches are only scored using the point of the blade. Like foil, sabre uses the convention of right-of-way to determine who acquires the touch.
The term sabreur refers to a fencer who fences with a sabre. Sabreuse is the female equivalent.
