Rapier

Rapier (German Rapier, from the French rapière, originally a Spanish espada ropera is literally a "sword for the clothes," that is, worn with a civil dress, not with armor, distorted in the French la rapière - mostly stabbing the blade weapon.

This is a kind of sword, in the original meaning of a long "civilian" sword.
