Torben Flindt, in his chapter on arms from Bukhara ( "Islamic Arms and Armour" Robert Elgood, Ed. London Scholar Press, 1979) mentioned that Bukharan handles were characterized by 5 large rivets.
The closest to the Bukharan are the Afghani arms: geographically and culturally ( Northern Afghanistan, including Mazar-i-Sharif are ethnically Uzbek).

Here are 5 Afghani swords: pseudo-shashkas, Khybers and a smaller Choora. In all, there are 3 rivets ( large or small). All are arranged in a vertical order as 1 x1 x 1.
Next, are Bukharan ( for sure) saber ( Mechanical Damascus) and a "Khyber" - like large dagger, most likely Bukharan (Wootz).
Both have 5 rivets ( pretty small): 2 x 1 x 2 configuration.
Are we to accept that no matter the size of the rivets, the 2 x 1 x 2 configuration is a unique and definitive sign of the Bukharan origin?
