I have a knife that I posted here some time back, which has what appears to be Arabic writing. I tried cross-checking it with various alphabets (Arabic, Urdu, etc.) in Wikipedia and couldn't find anything that seemed to be a direct match. However, a couple of the characters on your knife perfectly match a couple of characters on mine (just above "file Steel"). I don't know what that means, but I'm double curious now.
The knife I have is rather corroded, but the tang stamps on it are in English rather than Arabic (or whatever that language is). So yours is even more interesting in that regard. Frankly, I'm a little jealous
--if you ever decide you no longer want that knife, I'd be interested--I'm putting together a collection of folders from around the world, and even if I don't know for sure where it came from, I'd love to make it part of the display.
