Grit numbers are a sequence, not a single choice · review
The only stone set here that includes a flattening stone — the consumable nobody anticipates — with published dimensions and a bamboo base.
What we would actually buy The flattening stone is what makes this a set rather than two stones. It is the part people discover they need eighteen months later.
Two double-sided water stones measuring 17.8 × 5.6 × 2.8 cm (7 × 2.2 × 1.1 in), covering 400, 1000, 3000 and 8000 grit, on a bamboo base with rubber feet — and a flattening stone.
The reason to choose this set. Stones dish in the middle with use, and a dished stone cannot produce a straight edge. Everyone discovers this eventually; this set anticipates it.
17.8 cm (7 in) long, which is shorter than a 20 cm (7.9 in) chef’s knife. Workable — you sharpen in sections — and a longer stone makes holding the angle easier.
Ten to fifteen minutes of soaking, stated. Once a stone has been used with oil it cannot go back to water, so a water stone should never meet oil.

Water stones wear where you use them, which is the middle. A dished stone produces a curved edge no matter how well you hold the angle. Flattening returns the surface to true.
It is shorter than a 20 cm (7.9 in) chef’s knife, which means the blade is worked in sections. It is workable and a longer stone is easier.
8.1/ 10
The flattening stone is what makes this a set rather than two stones. It is the part people discover they need eighteen months later.
Someone who intends to keep sharpening for years rather than once.
