Werner Fisher & Manfred A. Zirngibl wrote in their book Afrikanische Waffen: “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.”
The back side of the blade was used as a machete for cutting. It was believed a person remained “aware” for some time after decapitation. As a result, the deceased final sensual experience was flying through the air to meet his or her ancestors. Executions were not judicial events meant for murders or criminals. They were events carried out for ceremonial purposes and the chosen were invariably slaves.
