Eastern Jambiya -Tourist or Tribal Vintage?

[ALEX]

Here's an Eastern dagger recently seen on eBay. Obviously neither antique nor weapon. Likely a 20th Century tourist grade or vintage ceremonial creation. The material is likely tin, and stones are aghate (aquick) glass imitation. It has some Kurdish, and also tribal Central Asian (Turkmen?) look. I have a feeling that I've already seen similar dagger somewhere, but cannot remember the source. Any ideas/opinions? THANKS!
