I've won this little knife in a lot, my main interest was for an other knife, but after a little bit of TLC it's a small beauty, very well made, cow or goat horn scales, fine copper bolster and a very well worked blade.
I am not able to pinpoint the exact origin. Greek, Black Sea, Bulgarian, Balkan? I don't think I have seen a similar knife before.

It's 21,5 cm overall, blade 12 cm, blade is 3,5 mm thick short after handle scales, weight: 63 gram. Last picture shows it together with a Faca de Ponta and a Canary Island knife from the same auction for size comparison.
Is someone able to tell me more about this knife? All comments are very welcome.
