Japanese knives are thin and hard, and most makers recommend water whetstones over pull-through or electric sharpeners. A good set covers three jobs: a coarse or medium stone around 1000 grit to set the edge, a finer stone from 3000 to 8000 to refine it, and sometimes a very fine stone for a polished finish. Two practical details matter as much as grit. First, whether the stones need soaking or only a splash of water, since splash-and-go stones are ready in seconds. Second, the base or holder, because a stone that slides on the counter is hard to use well. Stone size counts too: a long, wide stone makes sharpening a 240 mm gyuto easier. This guide compares six sets by grits, stone type, base or holder, soak or splash use and stone size, as each listing states them.
