bansidthe, the stone I use the most is the really coarse one on the Norton set, I don't have a belt grinder and need to get the initial bevels on the edges and that cuts them pretty good, had the water stones and they are real nice and I would reccomend them also, Kings are pretty good ones. But they do wear fast and you need to re-surface them more often, that's taking the stone and a glass plate, put a piece of sand paper, 150 grit or so, and wet it down, rub the stone around on the paper to true it up.
The water stones aren't as large as the Norton set, at least I haven't seen them offered that big.
I use the Spyderco Flat ceramic stones next and then a strop to finish it off.
