One last comment about the blade pushing water across the hone. This is a great visual indicator as to whether the bevel is properly set or not. If the bevel is there, the water will push out evenly from the edge of the blade across the entire span of the blade against the stone. If you have any trouble spots, you will see lags in the wave of water or no water pushing at various points instead.

In that first Naniwa video, he also shows how to put some very light downward pressure on the blade (above the trouble spot) with the index finger of your off hand to get a dull spot to come around. This is a very handy trick!
