No, you're not (completely) wrong...as there is a little more than meets the eye to it.
Cold weapons used in the Ottoman Balkans, moreover Bosnia, Albania and Greece would not have a hanging ring as they would be carried in traditional scarf, wrapped around a man's waist, which functions as a belt.

The one you are refering to is more a "show" piece of a rich merchant or an aristocratic of a lower rank, or a lady's dagger (as can be found in Serbia between 1860-1900).
Serbia were from approx. 1862 pan-Slavism turned their eye more to the west than the Ottoman east.
Hence influence and contact in these border erea's with Austria, Hungaria and their Slav brethren ( Russia and others like the sokol movements ) would cause the introduction of other practical ideas and fashion as f.i. some of these rings.
