Mahratt, an excellent observation. You're right. I guess this is just a (hunting?) knife with the Uzbek-styled scabbard; they fit well but could be a mismatch too.
Have you seen similar? The scabbard is Uzbek but I am curious if the knife is made in Russia, Uzbekistan, or elsewhere?
I doubt it's a mismatch. I think I see abalone inlay on the bolster as well as the scabbard.
