Swords wound girls (9)
I believe the answer is:
cutlasses
'swords' is the definition.
(cutlass is a kind of sword)
'wound girls' is the wordplay.
'wound' becomes 'cut' (cut is a kind of wound).
'girls' becomes 'lasses' (lass can informally mean a girl).
'cut'+'lasses'='CUTLASSES'
(Other definitions for cutlasses that I've seen before include "old naval weapons" , "swords" .)
