Little knife for identification

[Sajen]

After years of collecting there come sometimes knives which I never have seen before like this little fellow which crossed my way recently.

Is someone able to place the origin of this little knife? Handle form reminds puukko knives from Sweden, the ferrule reminds Chinese knives, the bone ring at the handle resembles some African knives I've seen.

Attached are the sellers pics.

All comments are very welcome!
