Hi user24:
Welcome to the EAAF.
This is indeed a recently made knife from West Africa. A few years ago I had an international student who brought several of these knives of varying lengths from Ghana as a present. The tooled leatherwork is actually quite attractive but the knives have poor non-functional blades.
While I know they are being sold now in Ghana, I can't really give you a more precise geographic region in which they are made. Others here can probably give you more accurate information.
Attached are pictures of several that I received from my student.
Regards,
Ian.
