Chop, hack (3)
I believe the answer is:
hew
I believe this clue is a double definition.
'chop' is the first definition.
(to hew is to chop or cut down)
'hack' is the second definition.
(I've seen this before)
(Other definitions for hew that I've seen before include "Chop or cut with axe" , "'Cut, fell or shape (3)'" , "Shape wood, as with an axe" , "Cut with blows" , "Carve with axe" .)
