Ignore girls' weapons (9)

Ross

I believe the answer is:

cutlasses

'weapons' is the definition.
(cutlass is a kind of weapon)

'ignore girls'' is the wordplay.
'ignore' becomes 'cut' (synonyms).
'girls'' becomes 'lasses' (lass can informally mean a girl).
'cut'+'lasses'='CUTLASSES'

(Other definitions for cutlasses that I've seen before include "swords" , "old naval weapons" .)

I've seen this clue in The Everyman puzzle in The Observer.
