Lovely looking stone, Dobel, and I love your enthusiasm.
Keep in mind that using water only on most coticules does not do all that much to increase keenness, it's mainly to slightly refine and smooth out an edge. It also works as a touch-up for razors that start to feel less comfortable.

What is increasing the pressure from the tap supposed to do? I've heard about finishing under running water (not my favourite, as I found no difference compared to not using running water and it kept running down my elbow) but that is new.
