North African knife

[SLS]

Hello.

I recently acquired this knife. I strongly feel that it is North African, Algerian maybe? There is no scabbard, the blade came covered with some old deteriorated varnish, probably damar or something similar. Where it is not damaged, the blade is still very sharp.

Not so sure about the bone handle - kettle, maybe?

Also, no idea about the time when this item was made.

Comments and some more information will be highly appreciated and very useful.

thank you, in advance
