African Throwing Knife for ID and comment

[Luc LEFEBVRE]

Jan Elsen in the book "De Fer et de Fierté" says that the copper dot seems to be a production of the north of the territory of the Ngbaka Mabo, maybe the southern Gbaya.
The production of this type of knife began around 1900 to 1960, after the 2WW the quality is lower.
The X on the blade is the symbol of the spider a totemic animal for the Ngbaka Mabo.
