SWORDS!! Of course they're swords! THEY'RE STRAIGHT - as a stick ;).

I'll try to make edit in my last post to not mislead others!!

(stupid me) :o

They called it Arabic, and even translated it, so I don't know what's wrong. Maybe the translation was made by second person, and author wrongly called this script as Arabic?

yes, michal, you dont fail to impress!
absolutely wonderful, especially the second sword.
i spent the day in a friends library, which is pretty much complete in all aspects of arms (where mine tends to concentrate on a very small section).
i found some interesting things, including a full article written on these sword blades by a respected academic, and hints of another which i ran out of time before i located it.
cant tell more as i was on something else at the time, but will have the articles sent to me soon. sorry, in my rush i didnt even take details as i knew i would have them at my leisure soon.
again, thank you michal for sharing your access to such fabulous pieces.

The inscription on the blade on the last picture says in persian : Ey tigh keh az to khasm e din kam bada

Roughly it means You/oh, sword/blade who fade the enemies of the religion
