Naniwa Advance (formerly Super Stone) is not quite as aggressive as its big brother Chocera Pro, but it clearly wins in terms of user comfort.
Advance is a Splash & Go stone: a light splash of water is enough, and long soaking is not required.
The stones are slightly softer in structure, giving a pleasant and highly controllable feel — without excessive, uncontrolled slurry formation.
The result is very consistent and predictable. Many consider the Advance series to be among the most comfortable stones on the market for home use.
Advance performs particularly well with Western knives (≤ 60 HRC).
However, the 400 grit included in the set is sufficient for basic maintenance of harder carbon steels as well, so its usability is not limited to softer steels only.
The package includes:
- 400 grit – repairs and initial sharpening
- 1000 grit – primary working edge
- 3000 grit – finishing and cutting feel
- Naniwa stone holder
- Suehiro 280 flattening stone
A well-balanced set both as a first proper sharpening kit and as a reliable tool for more experienced users.

NOTE!
"Splash-and-Go" stones do not tolerate prolonged storage in water. Use water only as much as the stone requires. Do not submerge the stones in a water basin. After sharpening, immediately wipe the stone clean with a towel. This keeps the stone looking tidy and initiates the drying process. Place the stone where it does not touch a solid surface. Let the stone dry horizontally, for example, by placing it over a pen. Allow the stone to dry slowly and peacefully without additional heating. Do not expose the stone directly to sunlight, and do not let the stone freeze while damp. The drying process takes more than a day. Store the stone protected from impacts, for example, in its box without the possible original foam padding. Please do not put the stone in a plastic bag while still damp.
