The fierce Chopper pictured above is linked to the Ababua people of Africa. Carved into the ivory handle is a deep, wide groove that wraps around the center. The blade is made from iron with three circular cut outs in a row. Beside those cut outs, on each side, are three prong shaped iron protrusions. The length of the blade bends into an L-shape and ends at a sharp point.
