Sword with a blunt end (4)
I believe the answer is:
epee
'sword with a blunt end' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for epee that I've seen before include "It may offer riposte" , "Another fencing sword" , "Use it to fence" , "Olympic event" , "Rapier" .)
