Cut off whip-handle (4)
I believe the answer is:
crop
This clue is a triple definition!
'cut off' is the first definition.
(I've seen this in another clue)
'whip' is the second definition.
(crop can mean a whip)
'handle' is the third definition.
(I know that crop is a type of handle)
(Other definitions for crop that I've seen before include "Expanded part of bird's throat" , "Produce - short hairstyle" , "Reduce" , "supply" , "The handle of a whip, or part of bird's neck" .)
