Sickle

From Wikipedia, the free encyclopedia

Using a sickle

A sickle is a curved, hand-held agricultural tool typically used for harvesting grain crops before the advent of modern harvesting machinery. It consists of a curved blade with a short, one-hand handle attached. The inside of the curve is sharp, so that the user can swing the blade against the base of the crop, catching it in the curve and slicing it at the same time. It is sometimes referred to as a 'grasshook'. A similar tool is the scythe. The most noticeable difference between a sickle and the scythe is the shape of the blade a Scythe blade is more linear whereas a sickle blade is more in the shape of a C with a point at the top.

A blade which is used to cut the silica-rich stems of cereal crops acquires a characteristic sickle-gloss, or wear pattern. When this pattern appears on ancient stone tools, it can indicate early use or development of agricultural use.
