Bolas
Bolas or bolases (sing.: bola; from Spanish and Portuguese bola, "ball", also known as a boleadora or boleadeira) is a type of throwing weapon made of weights on the ends of interconnected cords, used to capture animals by entangling their legs. Bolas were most famously used by the gauchos, but have been found in excavations of Pre-Columbian settlements, especially in Patagonia, where indigenous peoples (particularly the Tehuelche) used them to catch 200-pound guanacos and rheas.
