I believe this is a variant spelling of EPEE, which is a sword for dueling.

A highwayman sword is commonly referred to as a rapier. It is a slender, sharply pointed sword designed for thrusting attacks, commonly associated with dueling and self-defense during the Renaissance period in Europe.

Duels have been fought in the West for over a thousand years. As such, most types of personal weapons have been used at some stage. Early German fencing manuals show judicial duels taking place with special spiked shields.

Specific styles of sword designed for dueling include the dueling sword or epee, the Italian dueling Sabre and the German schlager (a type of Sabre).

The last duels fought in Europe used dueling swords closely resembling modern fencing epees (which were developed to train for such duels). Films of some of these later duels exist.

Epee is a dueling sword. EMP-35 is a German sub-machine gun. Elkins is the name of an automatic rifle.

Mercutio was in awe of the new fashion of dueling with a rapier because it allowed for more skill and finesse in combat compared to the traditional broadswords. Rapiers were lighter and more flexible, enabling duellists to showcase their precise movements and technique. Mercutio admired the artistry and style that came with this new form of dueling.
