Ax (3)
I believe the answer is:
hew
'ax' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hew that I've seen before include "Carve out of wood or stone" , "'Cut, fell or shape (3)'" , "Shape wood, as with an axe" , "Chop (wood)" , "Cut with blows" .)
