Lumberjack's chopper (3)
I believe the answer is:
axe
'lumberjack's chopper' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for axe that I've seen before include "flower in Devon" , "Sack with cleaver?" , "Chopping tool with heavy blade" , "saw alternative?" , "Fire weapon" .)
