The term 'saber cousin' is a reference to the fencing sport of epee, which is one of the three weapons used in fencing. The other two weapons are foil and saber. Epee is the heaviest and longest of the three weapons, and is characterized by its triangular cross-section and large bell guard. It is also the only weapon in which the entire body is a valid target. The term 'saber cousin' is used to describe the epee, as it is similar in shape and size to the saber.
