Eagle's grabber (5)
I believe the answer is:
talon
'eagle's grabber' 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 "Raptor's claw" , "Holding part of flier" , "Large claw" , "Part of hobby" , "part to make savage cuts" .)
