Another owner of a K02 asked whether the two black "stops" could be opened and used as clamps. The short answer is, yes.
You can clamp a blade to the upper surface of the table. Just remember that to sharpen the other side of the blade you will have to loosen the clamps, flip the blade and reclaim to the table. While this is slow, it would be the solution for users who have great difficulty working the stone with first one hand and then the other.
