i'm surprised JWW doesn't sell them, given their clown car of offerings from other places.
They do sell the stone that is a really nice stone (well, they market it as a "takenoko" 7000, but I see it's actually a 6000 stone). However, as with many things, it doesn't take much time to find it for less.
But the dizzying array of 4000-8000 stones they have, as well as the bunch of 200 grit range stones leaves me spinning. Most of the explanations do nothing to decipher what works with what.
Otherwise, most places here have one or two selections of artificial stones, and they mix in a bunch of things other than waterstones.
one aside, though, I have not used the coarse stones of the bester type, but the medium stones cut plain carbon steel and japanese irons very fast and hold their flatness well, and leave a very even scratch pattern. That flatness is extremely important when sharpening a hard japanese 70mm iron freehand, to lessen the amount of time spent on the next stone. I would bet there are a lot of japanese irons that aren't as sharp as they should be because of a 1000 stone that is not quite flat.
As for speed, though, no more than exists in shaptons and besters in the 1000 range is really needed with japanese irons, the flatness is more important.
For western tools, I literally take one side-sharpening stroke on a shapton pro 1000 with a freshly hollow ground chisel, and then probably 15 strokes with a 15k pro stone. If the stones cut faster, I'd just waste off more. If it takes more than a couple strokes to raise a wire edge on a chisel, I go over to the grinder and do a new primary, which takes less than a minute.

Unleaded tastes a little tangy, supreme is kinda sour, and diesel tastes pretty good.
