I am less convinced by the possibility that it is a spearhead fixed to a knife handle, for a very simple reason: African spearheads are almost always "female", while knives always have a tang that enters the handle. .. doesn't it seem to you too?

Thank you very much Duccio!
I have also contacted Wolf-Dieter Miersch who also stated that it's Lega knife and since the Lengola people are neighbours it will be one of this both possibilities.
Here is a Lega knife from his site: http://www.africanarms.com/gallery?9-lega-sword-56-cm which I've seen by my research but was jarred by the small iron pin in up from the handle!
He stated that these knives come with this pin but also without.
And yes, you are correct, African knives have nearly always a tang.

Best regards,
