Flail (weapon)
The term flail refers to two different weapons: one a two-handed infantry weapon derived from an agricultural tool, and the other a one-handed weapon. The defining characteristic of both is that they involve a separate striking head attached to a handle by a flexible rope, strap, or chain. The two-handed variant saw use in a limited number of conflicts during the European Middle Ages.
The two-handed flail is a hand weapon derived from the agricultural tool of the same name, commonly used in threshing. Only a limited amount of historical evidence exists for their employment in Europe during this era. These were deployed in Germany and Central Europe in the later Middle Ages. This weapon consists of a hinged bar connected to a longer shaft (see illustration, to the right).
In Korea the flail as an agricultural tool is called "dorikke" but as a weapon, it is called "pyeongon". The Japanese term for their equivalent of the ball-on-a-chain bludgeon is "rentsuru", while the Chinese version's name translates vividly into English as meteor hammer.
