it is a boan or bonan traditional knife,, although this one may be a chinese copy,,,,,,,,, bonan are , i think the smallest group in china,, anyway most chinese who know of them know mostly only they have good knives,,
a guy on the british blades forum,, had a good collection of older ones ,,

id say this is a chinese copy,,
the bonan are moslem people living somewhere just north east of tibet,, the speek a mongol language but ar emore as the setteled locals in the area,,
normaly their knives are of a rather high quality, and ushaly they have good laminated blades,,
the main difference to these and the other mongolian form and the tibetians knives it the different form of hanger and the bronze sheaths,,
the chinese have copied these , and mongolian and tibetian knives and massproduced them over the last 200 years or so,, many of the knives the mongols and tibetians used were chinese made, as the chinese could make it cheaper,, and with interesting materials , like ray skin,, which ,, isnt vary common , in say tuva,, or mongolia,,
the native ones generaly have better steel blades,, and the chinese ones come with things like chopsticks , pickel forks,and chinese decorations on them , chinese seem to have been oblivious to the natives taste,,
