Foil alternative (4)
I believe the answer is:
epee
'foil alternative' 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 "Bit of fencing" , "sports equipment" , "Use it to fence" , "Fencing sword similar to a foil" , "Fencing sword, heavier than a foil" .)
