Its definatelly not Mongolian, it is an Afghano-Pakistani Lohar. However this seems the most solid type, the non-composite, as in oposite of the folding type. I warn you, the effectiveness of the Lohar as a combat instrument has been highly debated, most people however agreed about the lack of lethality.
Andrew, you brought good memories to the table, that thread, that person, Smilodon Fatalis, fuhgetaboutit...
This is likely the most ornated Lohar I've seen so far!
