Reaper, gutless: sarcastic, yet handsome (6)
I believe the answer is:
scythe
'reaper' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scythe that I've seen before include "Manual hay-cutter wielded with both hands" , "Manual tool of reaper" , "Grass-cutting tool" , "Large sickle" , "It's useful for hacking" .)
