This very good dagger is coming from west Africa. Mid 20 C. and of good quality. Curved blade 7 ½ inches long of flat diamond cross section with 1 inch ricasso. Black horn and bone handle and brass / copper scabbard. Total length 12 ½ inches. Very good condition. Sharpening and grinding signs on the blade. A similar dagger in the British Museum is described as coming from the Bissagos ( Bijagos) Islands, a group of islands off the coast of Guinea – Bissau, but the attribution to these islands is questionable.
