: 
happy Eid el Fitr / Bayram mubarak Olsun 
hope you and ofcouse other Forum members can help me as I am puzzled.
This dagger bought at an auction was described as :
Turkey - 19th century - dagger, 
With wootz blade silver kofgary 
Horn hilt , silver Leather scabbard 
to me it could be 20th century as well but it certainly is Ottoman.  
My question is ... from where..? 
Some characteristics indicate perhaps Surmene ( the 2 small fullers at the blade) but the horn blade and more important the star/sun sign I have seen on Bosnian daggers, specially from Foca...
 Any idea? Your opinion  about the dagger in general is most highly appreciated ! thnx a lot
