African knife with copper (?) blade. Info requested!

[Pieje]

Definitely African, probably central Africa.
I own several copper bladed knives and spears. These are not suited to be used as a weapon by the softness of copper, but are indeed symbols of status, used as money etc.

The last knife with scabbard is not very old, and might originate from North Africa.

Thanks Pieje!
Regarding the last knife, being of recent manufacture, what is the reason for the copper blade...prestige or a cheap trinket?? Given the cost of copper vs. steel, seems a steal blade would be the more economical choice, no?
