Thanks for the close ups.  Now I see that this is truly more unusual than I originally thought.  Though still leaning Balkan, it now does not seem as Balkan as I thought now that I see these later picture close ups.   
 
Regarding the 2nd example, what region does it come from in the Ottoman Empire? 
 
Also I agree with Kubur regarding the fish/monster scabbard finial.  Quite common on Ottoman yataghans, both on sword and dagger styles.
