Husband has two opposing points to axe (3)
I believe the answer is:
'axe' is the definition.
(I've seen this in another clue)
'husband has two opposing points' is the wordplay.
I cannot quite see how this works, but
'husband' could be 'h' (abbreviation) and 'h' is found within the answer.
'points' could be 'ew' (east and west, two compass points) and 'ew' is found within the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for hew that I've seen before include "Shape wood, as with an axe" , "Chop; sounds like colour" , "Chop (wood)" , "'Cut, fell or shape (3)'" , "Cut with blows" .)
