The “boleadora” is a throwing hunting weapon that consists of one, two or three stone balls, held together by strings or twines (made of tendons, leather, or any other material that would allow its production). It was used by indigenous peoples from America since pre-Columbian times, and it was later adopted by the “gauchos”. There are different types of balls. The most common ones are: 1. The ones without a groove. They were smooth pieces and they were probably used with a leather wrapper attached directly to the twine; 2. Those with a perimeter groove which fit the rope or twine; 3. Those with two grooves. Interestingly, the “boleadoras” became very popular, so indigenous, mestizos and Spanish people used them as a sport or for fun.
