Harvesting implement (6)

I believe the answer is:
sickle
'harvesting implement' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sickle that I've seen before include "Farmer's hook" , "Harvesting implement" , "With a hammer, it forms a Communist symbol" , "Crescent-shaped hand tool for cutting corn" , "Farm implement" .)
