Hi Both,
I'm like you very confused.
For sure Balkans, in between Bosnia and Bulgaria.
Maybe Macedonia? It's in the middle...
Another funny stuff is the big crack on on the both side of the grips.
The grips are fixed with the same little nails that you can see on the joint.
To my opinion, the grip was broken before the craftman fixed it and he had to put more nails to maintain the different parts.
It reinforces the idea that the grip was done by a knife specialist more than a guy used to do grips for swords...
Is it make sense for you?
Best,
Kubur
