Although I do finish on a dried slurry-paste, and not clean water, it leaves a very sharp edge. Also, it leaves a very uniformly shiney bevel that is kind of hazy with no appearance of scratches. I know the visual appearance of the bevel doesn't tell you much about the edge and isn't always important, but I really like how uniform it looks after I'm done.
