Hawk's claw (5)
I believe the answer is:
talon
'hawk'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 "Bird's claw" , "E.g. hawk's claw" , "Holding part of flier" , "Claw; undealt cards" , "Part of hobby" .)
