Kurdish, Turkish, Balkan Jambiya (and Wootz)

[Atlantia]

Thanks for the replies gentlemen.
What I'm trying to do is see if there is a way to identify region specific features within the variations of these daggers.

The generic type is Kurdish but clearly there are very specific sub-types.

For instance, the dagger I have pictured has four Silver Turkish coins, so is presumably Turkish-Kurd.
