A Lot of African Weapons

[Duccio]

Hi,
the largest knife, the one in the center of the first photo, I think it is a very old and worn Congolese Konda (not Kuba).
Here you can see a similar one.

The main feature of many konda daggers was the lack of the tip, which was flat or, more often, rounded.
In this way the dagger remembered what had been established by a great ruler of the Kondas, who imposed to remove the tip from the swords of the warriors, to mean that the Konda federation was not afraid of being attacked by any of the neighboring peoples.
What seems strange to me, in your dagger, is the handle, which is different from the usual.
Regards.
Duccio
