Olympic fencing event (4)
I believe the answer is:
epee
'olympic fencing event' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for epee that I've seen before include "Rapier" , "there's a point to it" , "sports equipment" , "sharp-edged implement" , "Foil for riposte" .)
