Mysterious Blade

One of the chefs who works at my family's restaurant moved in across the street from me. Pretty cool guy, he is. He also kinda collects swords and such on the side. He's also the guy I got my chokuto from.

Anyway, I saw this here sword and was baffled of what design it is. I looked all over Wikipedia, but I still couldn't find a picture of a sword or dagger that matched this. And that's why I posted the picture of it here.

Does anyone know what this kind of sword is?


*UPDATE*

Thanks to my good friend , it turns out that this particular sword is an Arabic Warrior Short Scimitar. And I always had a hunch it looked Arabic.
