Bola
A throwing weapon that entangles legs with weighted cords
The bola is a throwing weapon of two or three heavy stone or metal weights joined by cords, which on being thrown spins through the air and wraps around the legs of its target to bind its movement. Its chief trait is that it is a capturing weapon, made to seize rather than to kill. It is a hunting weapon developed by the indigenous peoples of South American Patagonia, used mainly to hunt fast grassland animals such as the rhea, the South American ostrich, and the guanaco, a wild relative of the llama. It later grew more famous as the gauchos, the South American cowboys, used it to drive cattle. Each weight is about 200 to 500 g and the cords about 60 to 100 cm, and it was used as a weapon of war too, fielded by the army of the Inca Empire.
