A stone knife I've found during the recent kayak trip. It's been laying on top of a mole tunnel, so the little guy dug it out for me.
The region seems to be full with neolithic settlements, and this one has apparently been thoroughly studied long time ago. Still, it seems that one can still dig somehting out.
