That's a fairly normal Tibetan dagger on Therionarms; the name I have is thi, though I've seen another I can't recall; the general shape of the handle is rather similar, no?
Then there's the sheath (with frontal scabbard slide?), the chisel bevel (Tibetan daggers are usually wedge-section, I think, although this could be a special purpose knife of some sort, I suppose, or from a small ethnic group, etc.....), and the carvings on the handle, which are what remind me of Ainu work. That coin isn't tripping anyone's memory, huh? I've seen it before, and might even should know where it's from......
Thanks for the link, Rick; it really simplifies things
