Sorry for piping in late. 
 
My example has a mixture of decorative elements: niello decorations in the Circassian style and  a characteristic South Caucasian/Turkish bar on the handle. 
 It suggests one of the two possibilities:  
1). It came from the Turkey-dominated  South Caucasian area ( such as Megrelia); or 
2). It is  the so-called "muhadjir"work by Circassian masters after their exile to the Ottoman Empire. 
 
I have consulted with Kirill Rivkin, and he confirmed the Turkish connection. 
 
 
Kubur, I might have misunderstood your question: if you were looking for a purely Turkish example, mine is not what you were looking for.  If, however, you wanted to see Turkey-influenced one, mine would fit the bill.
