Raptor's grabber (5)
I believe the answer is:
talon
'raptor'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 "One hooked on bird" , "Sharp hooked claw" , "one that grips" , "part to make savage cuts" , "Claw; undealt cards" .)
