Very, very interesting. I am leaning towards hand held knife/scraper, or practice piece also. The notches on both ends are very interesting, but the "stems" between the notches look too thin and short IMO to have been for hafting? If I imagine a shaft the width of these stems being hafted to this piece, it seems they would be too thin or flimsy to have been able to withstand the leverage needed to work the knife with such a handle? Just some thoughts, I like thought provoking pieces.
