Just say he's a craftsman (6)
I believe the answer is:
wright
I believe this clue is a triple definition!
'just say' is the first definition.
(I've seen this before)
'he's' is the second definition.
'a craftsman' is the third definition.
(wright is a kind of craftsman)
(Other definitions for wright that I've seen before include "Maker or repairer" , "Frank Lloyd ... (aviator)" , "Wilbur and Orville --" , "One makes things, plays say" , "One of the first to stay up" .)
