A few weeks ago i bought this in a bundle with two aceh swords.
However, this one is clearly not from SEA
It looks a lot like a koumiyya from north africa with a very long straight blade.
Blade length is 42cm and overall length is 56cm -- almost a short sword.
From what i recall these things are called "janwi" but i didn't find much information about them, except that a lot of them were made from european bayonet-blades. So i thought, i better ask here
Best Regards,
Thilo
