Interesting piece. Is the blade curved, spoon like? It doesn't appear to be, that would rule out a marrow scoop. Plus i've never seen one with a carrying case or sheath and the blade end isn't right. Need a size for reference, what are the dimensions? Also can you make out the lettering on it?
All I can see if MADE in ITALY and A. P(or B)ANEN? _PPEMANA? Try and figure out the correct lettering. Camera glare prevents me from seeing it correctly.
