Great to see this example.  I have one without a scabbard that I thought was Eastern Chinese/Tibetan/Bhutanese.  It's nice to see i was close, but even nicer to know exactly what I have. 
 
You mention that yours is mono-steel.  Are you sure?  Mine has Tibetan style hairpin folding, and it seems as though yours might as well.
