Awkward punch cuts boxer Naz (3-6)
I believe the answer is:
ham-fisted
'awkward' is the definition.
(I've seen this before)
'punch cuts boxer naz' is the wordplay.
I cannot quite see how this works, but
'punch' could be 'fist' and 'fist' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ham-fisted that I've seen before include "Lacking 5 across" , "I'm shafted, being clumsy" , "Clumsy, awkward" .)
