Naniwa Professional #600 grit whetstone is used for coarse sharpening of damaged knives (eg, broken tip, chips or nicks in the blade), or for totally blunt blades.
The Professional* Stone is the new high-tech line of sharpening stones from Naniwa. It is the hardest Japanese sharpening stone, therefore, wear is absolutely minimal and the lifespan maximum. It does not only sharpen well, but also sharpens quickly. Experienced users can really feel a difference with these stones.
The secret that makes these high-quality whetstones different from other whetstones is that they are bonded with magnesium and not resin. They have greater density of finely graded abrasive particles per unit of surface area than resin-bonded stones. Being harder, they wear slowly and will take much longer to develop a hollow. There is no need to exert any force while sharpening.
This is a splash and go stone and only needs to have its surface moistened slightly with water. If you do soak it, just briefly dip it in water for no more than 2-3 minutes.
Naniwa Professional Stones require more care than your average stone. When you are done with sharpening, just let them air dry so they can dry evenly. Do not expose them to heat. Store the stones only after they are completely dry in a dry, dark place. They should NOT be left to soak in water for prolonged periods and must be stored dry. Ignoring this advice may result in hairline cracks developing in the stone or the bonding material leaching out of the stone.
For easier sharpening, we recommend purchasing a Stone Holder (Sink Bridge) to ensure mess-free and a stable position of the stone during sharpening.
*Sidenote: Due to market expansion, Naniwa often changes the product name and its packaging - the Naniwa Chocera Pro stone is the same stone as the Naniwa Professional stone, with the same composition and characteristics.

Stone care & maintenance:
Soak the stone if required, keep the surface wet while sharpening, and rinse off slurry after use. Let it air-dry fully before storing. Keep stones flat with regular flattening, and avoid direct heat, freezing temperatures, and long-term soaking unless specified.
A flat sharpening stone is key to consistent sharpening. It helps you maintain the right angle, create an even edge, and sharpen more safely and efficiently. Use a flattening stone regularly to keep the surface even before sharpening.
Keep your sharpening stone performing at its best with the right accessories. Use a stone holder for stable, safer sharpening, and a Nagura dressing stone to refresh the surface, remove steel build-up and create slurry when needed.
