I believe this to be from the African Bali culture in the grasslands of Cameroon. I realize that I am leaving myself open to the REAL African experts and certainly welcome their opinions!
Don't think that the scabbard (came with it) is Bali, but probably came from one of their neighbors. Looks like a Tikar scabbard.
