These were found on a west coast public beach (Oregon/Washington border). Can anyone help identify these? 2 are sandstone. One appears to be an abraider (used to smooth the shaft of an arrow, bone? etc), The one with the holes (pits) is a rough stone but you can see swirl marks in each of them-as if someone was grinding something into the stone.

Thanks
