Raptor's claw (5)
I believe the answer is:
talon
'raptor's claw' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for talon that I've seen before include "E.g. hawk's claw" , "Hooked claw; cards left after deal" , "Bird's claw" , "Eg, an eagle's claw" , "a gripping one" .)
