Huge sword - Persia or Caucasus

[wolviex]

Hello all!

I have a question. On the pictures you can see a very huge sword - 110cm/43inch. long - it's bigger than sabre

The shape of the handle is like of Caucasian knives, the blade is quite solid, thick not cheap metal, but resilient, with fuller on both sides in the centre. On the blade are etched squiggles, and ornaments with letters or just pretending the letters (sorry no photo of this part).

Main question is: do you think it's Caucasian or Persian - like some catalogues described it. I'm sure it's 19th century, maybe even 2nd half of the century. But what was the purpose of such huge weapon - only ceremonial? It is made very solidly, just like the weapon for use, but its size seems to be ridicoulus .

I'm waiting for your opinions
Thank you in advance and regards!
