Rough-hewn (6)
I believe the answer is:
rugged
'rough-hewn' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for rugged that I've seen before include "Rough and uneven" , "Jagged" , "'Craggy, rough (6)'" , "designed for heavy use" , "Having toughness and determination" .)
