Bladed weapons (6)
I believe the answer is:
swords
'bladed weapons' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for swords that I've seen before include "Bladed weapons in north Dublin" , "Weapons from north Co Dublin?" , "Eg, rapiers, sabres" , "Steel weapons" , "Bladed weapon" .)
