The bola is a weapon with an extensive global reach and a long history of use. It has been used on almost every continent, from the tallest mountains to the lowest swamps. Primarily used as an impact weapon, the bola offers a secondary feature – entanglement. A lucky strike with this weapon will stun (or even kill) the quarry, and if that doesn’t work, the cords may ensnare them long enough for you to rush in with a blunt object and finish the job. A bola with three, four or five weights is most commonly associated with large bird hunting, such as geese, since their hollow bones are particularly vulnerable to strikes and their wings are susceptible to entanglement. Here are the steps to make your own hard-hitting bola.
