I acquired this object at an overseas auction some years ago. I initially thought it was a type of dance wand from the Solomon Islands but closer inspection established that was not the case. I have since made various attempts to establish what it is and where it was from but with no success. However recently I (by accident) found a similar object in the British Museum. It was amongst a collection of artefacts from the Kabyle people who come from a part of Algeria. It looked older but the carved decoration was the same as the questioned example. Its about 88cm or close to 3 feet in length.
It was listed as a Sword? or Fighting Stick? so the Museum did not know it's actual use nor what it was called.
I am just wondering if anyone out there night be able to enlighten as to this items use and what its correct name might be. I am assuming the Museum is right about it being Kabyle but there might be a ? about that as well.
