Ngulu (weapon)

It resembles the Khopesh, the sickle-sword of ancient Egypt, except that it has a much more massive blade, made of iron, with a non-cutting back and a semi-circular concavity. The handle, often surrounded by metal wire, ended with two large wooden buttons and a smaller one. It could be one or two blades and was used for capital executions by beheading (the condemned was kept seated, head extended and attached to a branch).:^[1] This design was selected for cult and execution knives. A knife was created which symbolized the inexorableness on the judgment and execution. This execution knife became a symbol of power and, in a few variations became a ceremonial knife for tribal chieftains. At executions, the condemned man was tied to the ground with ropes and poles. His head was fastened with leather straps to a bent tree branch. In this way it was ensured that the man's neck would remain stretched. After the decapitation, the head would be automatically catapulted far away.
