Writer's cut (4)
I believe the answer is:
hack
This clue is a double definition.
'writer's' is the first definition.
(hack writer is a kind of writer)
'cut' is the second definition.
(hacking is a kind of cutting)
(Other definitions for hack that I've seen before include "Kick on the shins" , "Crude cutting" , "mediocre writer" , "Put up with" , "Tired old horse" .)
