That is an adze. The stone tool was hafted to a handle and used sort of like a plane . Other ones are hafted at different angles depending on whether they were using it to trench dirt or plane a flat surface on wood.
Agreed, the one in picture is not produced by knapping, flaking or chipping but is ground away. In that case it was produced much later than than the ones I have covered.
The ones I have put up so far are from the Early Stone Age(ESA) to Middle Stone Age(MSA) yours would likely fall into the Neolithic.
It may even stem from as late as historical times.
