Bear's scratcher (4)
I believe the answer is:
claw
'bear's scratcher' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for claw that I've seen before include "Crab pincer" , "Hook of some birds and animals" , "Scratch - scrape" , "Hooked nail" , "Pointed nail on animal's foot" .)
