Hawk's weapon (5)
I believe the answer is:
talon
'hawk's weapon' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for talon that I've seen before include "One may be grabbing" , "Part of hobby" , "Tonal (anag.)" , "Eagle claw" , "Claw of a bird of prey" .)
