Naniwa Professional (Chosera) 600
- Product Code:P-306
- Availability:In Stock
The Naniwa Professional collection is the improved version of the Naniwa Chosera Stones. Naniwa improved the binding agent for the sharpening stones. What is unique is that Naniwa itself produces this binding agent. It is important that this is optimally matched to the grain size. The result is that the Naniwa water stones are better than most sharpening stones produced by other brands, even though the grain size is similar.
How to use Naniwa Professional Stones
The Professional Stone is made on the basis of bound magnesium. This is a superior production method that ensures the quality of the stones are unparalleled. The Professional Stones hardly absorb any water to make sure you only have to add some water before use. They don't have to be submerged in water. After use, it is key the stones properly dry at room temperature. Don't allow them to dry on the heater! Once dried store them in a dry, dark place. As such you prevent small cracks.
About Japanese grain sizes
Sharpening stones are available in different grain sizes. The larger the number, the finer the grain. The finer the grain, the sharper the results. When you start sharpening you start with the coarse grain and continue towards a finer grain. Steps of a factor two to three between the different grain sizes are ideal.
Indication for choosing the right sharpening stone:
Grain 400 to 600 : suited to restore the edge of blunt knives
800 to 1000 : to sharpen and maintain knives that are in good condition
Grain 2000 to 3000 : for sharper results than upon delivery
Grain 5000 to 12000 : for razor-sharp results

Q. Is this the new version of the Naniwa Chosera stone?
A. Yes, Naniwa changed the name from Chosera to Professional stone. It has always been their professional quality stone, now its name reflects its intended use. The same method of production that has made this stone famous has merely been updated to allow for tighter standards in grit tolerances.
Q. Will I need a flattening stone for these?
A. Yes. Though the Naniwa Professional stones are harder and will wear more slowly than many other water stones, they still require flattening. Our favorite flattening stone is the DIAMOND LAPPING PLATE HAPSTONE
Q. Will I need a stone holder to use these?
A. While a stone holder isn't required, using one is a good idea. A stone holder will help keep the water stone from sliding around and will raise the stone up off the work surface, which can be especially handy when sharpening knives.
