Rough to the touch or uncouth (6)
I believe the answer is:
coarse
I believe this clue is a double definition.
'rough to the touch' is the first definition.
(I've seen this before)
'uncouth' is the second definition.
(I know that uncouth can be written as coarse)
(Other definitions for coarse that I've seen before include "Rough, uncouth" , "needing refinement" , "gross" , "Boorish" , "Rought or crude" .)
