I don't know about this one, but it can be African.
I'm trying to get an axe into my collection which is still owned by a Dutch friend from Amsterdam. I handled this piece several times and although it looks rather 'fancy' for an African axe, it really is a good piece. (and I know, one day, it will be mine

)
It's the axe in the middle of the pic. My friend says it comes from Tansania.
