Cut rate (4)
I believe the answer is:
clip
I believe this clue is a double definition.
'cut' is the first definition.
(clip is a kind of cut)
'rate' is the second definition.
(I've seen this before)
(Other definitions for clip that I've seen before include "Film excerpt" , "Magazine" , "Extract; cartridge" , "Shorten" , "It can hold cartridges and hair" .)
