A sickle is a crescent-shaped blade with a short handle, used for cutting grasses and weeds; it is also known as a “reaping hook”. It’s a period charge, found as early as c.1340, in the arms of Zürnler [Zurich 323]. The blade is to chief, embowed to sinister, by default. For related charges, see pruning hook, scythe. See also knife.
