Kpinga
The Kpinga (also called the Hunga Munga) was a bladed throwing knife used by the Azande of Nubia. It would have been about 22 inches in length and had three different shaped blades projecting at different angles to maximize damage to the enemy. They were classed as "Court Metal", being produced under the patronage of the powerful Avongara clan, and distributed only to professional warriors and considered status symbols. It was also part of the dowry that a man must pay to the bride's family.
