Cut with an oblique stroke (5)
I believe the answer is:
slash
This clue is a double definition.
'cut' is the first definition.
(I know that cut can be written as slash)
'an oblique stroke' is the second definition.
(I've seen this before)
'with' acts as a link.
(Other definitions for slash that I've seen before include "Oblique stroke" , "Cut; reduce drastically" , "Punctuation mark" , "Make sharp, long cut" , "Cut as with a sword - /" .)
