Stubble cutter (5)
I believe the answer is:
razor
'stubble cutter' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for razor that I've seen before include "and 17 Down: Whisker-remover" , "Edge tool used in shaving" , "Stubble remover" , "Shaving implement" , "Bathroom implement" .)
