More info regarding this Georgian Kindjal

[Hatumesh]

Hi all,
I'm new here, so please bear with me...

The Georgian Kindjal in the pics is a....Georgian Kindjal. That's all I can say about it.
Can any of you add details regarding this specific one and also regarding this kind of dagger in general?

It's been ill treated for the past 50 years, hence the deep rust. I'd like to restore it and I need tips-and-tricks for that (not too profession - i'm doing at home with near-zero budget).

The hilt and scabbard are silver.

Thanks a bunch,
Hatumesh.
