The design allows you to turn the top knob, line up the inner and outer slots into the open position, and dip into grain or seeds. Slots are open to let grain enter. Then you turn the knob again, closing slots to capture the grain and pull the sample out.  It is precision made to have a nice snug fit between the inner and outer tubes. All three have a great patina the way they are They could be easily polished to a full brassy shine if desired.
