What type of throwing weapon is it?

A bolas 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 (South American cowboys), but have been found in excavations of Pre-Columbian settlements, especially in Patagonia, where indigenous peoples used them to catch 200-pound guanaco and ñand. The Mapuche and the Inca army used them in battle.
