Thank you Jens and Motan for your thoughts
Very interesting observations. I also do not recall seeing similar Shibriya, and also agree with Motan that this one appears to be genuine and real one, just smaller than usual. Some miniature arms were done quite well, but for display or novelty purposes and not to be used, and this becomes quite apparent when one sees or handles them. Some can also be seen here:

The subject Shibriya is not exactly in this category and somewhere toward a real weapon, small utility, child knife, etc. Hopefully others will have more info or references to this theory.
