It certainly is very old ... but what is it ?

This is the best i can get with my tired digital camera .
Two shots from the mark side and one from the opposite side.
This afternoon i visited someone much more enlightened than me in these things. He is pritty much convinced this piece is a locally made rustic haft weapon (pike) head ... not a butt, nor an African item .
On the other hand, he doesn't think this mark in the pictures is something intentional.
