From whence this Bichaq?

[serdar]

First “bichak” doesent necesary need to be from yatagan, there were shorter yatagan knives like that one, engravings on it are too close to hasrma to be of a yatagan, and sweeping of the blade sugest it is a knife not reshaped yatagan, it is probably from algere region not greek.
Also scabard has nothing to do with balkan, why everyone put things in balkan with that ease.
