Flails use to increase impact and can be used to strangle or to tangle an opponent’s limbs or weapons. The chain weaves a complex path; flails are difficult to use safely. The most common varieties of flail are, , , and.

Overview
A flail is usually made from two or more large sticks attached by a short chain; one stick is held and swung, causing the other (the swipple) 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 long by 3 cm in diameter, and the second stick being about 1 m long by about 3 cm 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.

Non-agricultural uses
As with most agricultural tools, flails can often be used as weapons by farmers who may lack access to better weapons. The flail is proposed as one of the origins of the two-piece baton known in the Okinawan kobudō weapon system as the nunchaku. The first recorded use of a flail as a weapon was at the siege of Damietta in 1218 during the 5th crusade, as depicted in the chronicle by Matthew Paris; tradition has it the man was the Frisian Hayo of Wolvega who bashed the standard bearer of the Muslim defenders with it and captured the flag. Flails were also used as weapons by farmers under the leadership of Jan Žižka during the Hussite Wars in Bohemia.

In ancient Egypt the flail was a symbol associated with the monarch, symbolizing his ability to provide for the people.
