two kindjals

[Rivkin]

Just wanted to ask if you guys have an opinion about these two pieces:

First one:

The signature is far too crude to that of Chilla. Arabic part of the signature is either missing or unintellegable.

Interesting beast. The first one nearly exactly like this (with a different master) I've got from Khevsureti where it was advertised as a "khevsurian satevari" (satevari is basically a large kindjal in georgian). The blade looks like chechen to me, and the way its decorated reminded me of Atagi. Size is definetely southern, but fits the chechen patterns as well. However the scabbard is most likely not chechen, but more like georgian (I had one from Tiflis like this), or even more to the south - iran, turkey ? like the seller suggests it is.

Since it's not the first time I see beast like this, does anyone know what it might be ?
