Ngombe knife (CONGO)

[Congoblades]

Lucky Luc , I like the copper inlay's very much, its on my wanted-list.
I do have simular knives from the Yakoma area in copper. According to H. Westerdijk, ijzerwerk uit centraal-afrika, group2 - fig 28, these knives are most probebly made by the Poto-blacksmith's?

Largest one is 48 cm
