interesting jambiya on eBay

[A.alnakkas]

Thanks Gene, I can only be sure with a hot needle test. The seller said its wood but it have alot of similarities with horn items and has some weight to it. The back side shows some fiberous octagonal shapes that I couldnt photograph properly without sunlight.

I'll clean the blade too but might not be worth it. Lovely patina on it and no rust.
