Nowadays, we often hear people say “I can’t sharpen a knife.” or “I would buy a new one if the knife becomes dull.” Also, cooking methods are becoming easier and only require minimum cooking tools. It is reflected in the good sales of simple sharpeners. Even if people want to cook with a very sharp knife, they might think that sharpening a knife with a whetstone is complicated and difficult, or even scared of handling knives. However, to whet knives is neither difficult nor dangerous. If you have one versatile whetstone at home, you can whet not only cooking knives but also various kinds of knives and blades you have. Even from the perspective of cherishing what you use, we’d highly recommend using whetstones.“Cutting” is necessary for our daily lives. Suehiro Corporation always try to produce versatile products, which can be used by everyone from expert users to homemakers. Above all, we make our best effort to deliver the quality products, which can be used by our customers safely.

Nagura Stone - #5000
Nagura Stone - #5000
Nagura stones are smaller sharpening stones constructed in a similar way to other Japanese water stones. They are used to dress the surface of a water stone of the same grit or finer, removing abraded material that can become embedded in the stone.
In the later stages of sharpening at higher grits, a Nagura stone can be used to raise a slurry on the water stone that can be worked to break down the abrasive particles, improving the finish and polish of the blade.
Please note that each grit of Nagura stone is for use on similar grits of water stones or higher. The #1000 stone is used for dressing #1000 stones or higher, while #3000 and #5000 can be used to raise slurry on similar- or finer-grit stones.
