Quarrelsome carpenter (6)
I believe the answer is:
chippy
This clue is a double definition.
'quarrelsome' is the first definition.
(as in having a chip on your shoulder)
'carpenter' is the second definition.
(chippy can mean a carpenter)
(Other definitions for chippy that I've seen before include "Oversensitive - traditional British food shop" , "who may want a good deal" , "Carpenter - touchy" , "Irritable; carpenter" , "Resentful" .)
