Is this anything?

Wow, i really got what i asked for from you guys.
With that info and the keyword "adze" i was able to search for more info on the net.
It seems that this type is a working tool, since the ceremonial adze should be colored and decorated, and the bridal adze has longer stoneblade.
Given this info i believe it's claimed origin and dating proofs true. I will probably try to place it with someone who appreciate having it in his collection.

The bone dagger is unfortunately gone because of it's bad condition.
It was a scary item to hold, it felt very magic and soulful.
Again thanks a lot
