Gene, it is really outstanding and rare Kindjal blade, congratulations!
I am by no way a kindjal specialist, but I am with TVV on his Turkish (South? Transcaucasian?) attribution. It is definitely not Kindjal from the North Caucasus, i.e. Dagestan or Chechnya. I will be back at home on Sunday and will try to find some clues in my books. I hope some Kindjal specialists will share their knowledge with us until then (by the way, where is Ariel's comment ?)
