Devious slash (7)
I believe the answer is:
oblique
This clue is a double definition.
'devious' is the first definition.
(thesaurus)
'slash' is the second definition.
(I've seen this before)
(Other definitions for oblique that I've seen before include "Slanted" , "Indirect - evasive" , "Slanting, indirect" , "This angle is obtuse or acute" , "Slanting, or expressed indirectly" .)
