A flail is an agricultural tool used for threshing to separate grains from their husks.
It is usually made from two or more large sticks attached by a short chain; one stick is held and swung, causing the other to strike a pile of grain, loosening the husks. The precise dimensions and shape of flails were determined by generations of farmers to suit the particular grain they were harvesting. For example, flails used by farmers in Quebec to process wheat were generally made from two pieces of wood, the handle being about 1.5 m (4.9 ft) long by 3 cm (1.2 in) in diameter, and the second stick being about1 m (3.3 ft) long by about 3 cm (1.2 in) in diameter, with a slight taper towards the end. Flails for other grains, such as rice or spelt, would have had different dimensions.
Flails have generally fallen into disuse in many nations because of the availability of technologies such as combine harvesters that require much less manual labour. But in many places, such as Minnesota, wild rice can only be harvested legally using manual means, specifically through the use of a canoe and a flail that is made of smooth, round wood no more than 30 inches long.
The flail is depicted alongside the “crook” as symbols of office for the crowned Egyptian Pharaoh. The flail symbolises the Pharaoh's role as provider of food for his people and the crook symbolises his role as the shepherd of his people. Both crook and flail also serve to link the Pharaoh with Osiris. Depictions of Anubis, the jackal-headed god of the embalming, also include the flail as attribute. The crook and flail are also major signs of the god of the setting sun and the ruler of the land of the dead: Osiris.
