Steal; small cut (4)
I believe the answer is:
nick
I believe this clue is a double definition.
'steal' is the first definition.
(nick can informally mean to steal)
'small cut' is the second definition.
(I've seen this in another clue)
(Other definitions for nick that I've seen before include "Steal (sl.)" , "chip" , "Take" , "Prison - cut" , "Minor injury" .)
