Rapier. Is said to have had distinct meanings at different times, and in ancient fencing to have been a long cutting broadsword; but for the last century, at least, the rapier has been a light, highly-tempered, edgeless, thrusting weapon, finely pointed and about 3 feet in length. At present, it is worn only on occasions of court ceremonial, and answers no other purpose than to incommode the wearer. In war a rapier could never have been of any service.
