I think this leather work is of Niger origin and you can find it in handicraft markets (souiveniers for tourists) min. from Mali through Ghana and Niger to Nigeria (including). The same leather work is used for production of other souveniers like frames for pictures, various boxes etc. IMHO, this knives are made for tourists (not for tribal use and not as a part of costume) and, I think I could say, their shape devellopped a little within the last 20 years.
Nevertheless, the same leather work has been used on the leather sheaths of a very ordinary, nevertheless heavy (industrially made) machetes worn/used by villagers (especially herdsmen) from that vast area. Currently, they use this nmachetes (without any tribal or other ornamentation and decoration) as a useful tool. But their sheaths are nice.
