Trabzon Surmene...
 And a very nice one!
 These knives had the most intricate system of fullers. The handle looks particularly nice and the suspension belt is a rarity. And look at the weave of leather straps at the top of the scabbard: doesn't it look just like Laz Bicagi? 
 Lew, I was always very happy about you limiting yourself to  African stuff ( because I do not collect them); why did you decide to cross the border? Looking for a fight, infidel invader? 
 
 
Well, on the other hand, I am glad you finally saw the light! Enjoy!
