Hair tool with teeth (4)
I believe the answer is:
comb
'hair tool with teeth' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for comb that I've seen before include "Toothed object for tidying hair" , "Rummage through" , "For use on hair" , "Device for tidying one's appearance" , "Ransack, scour" .)
