From 16th to 19th century there are only few styles of decoration that we can say they are defiently Greek. You see, a lot of invaders and a lot of cultures passed from this country. If it was not the description I could put this yataghan somewhere in Balkans. So generally.
Round ears is Greek sign. Brass hilt and scabbard was used more by Bulgarians. Flowers used everywhere. I am still learning Greek and Ottoman weapons so it is very possible I miss something.
It is only one reason I didnt bid on this yataghan. Greek or not it is ugly!
