400 grit is the coarse grit stone, which is used for chip repairs, thinning and reprofiling. It is not the first stone that one should get but it is an essential stone down the road. 

The Professional

The Naniwa Professional line is basically the overseas version of the Chosera line. The abrasive is basically the same as the famed Chosera line which is trusted by many professional chefs, woodworkers and sharpeners as the best splash and go sharpening stones. 

Compared to the Chosera (25mm thick), the Professional (20mm) is marginally thinner, and does not come with base, which is preferred by many as easier to store and carry around. It is also cheaper to ship thanks to the lack of base. 

  • Type: Splash & Go, do not soke for more than 15 minutes
  • Dimension: 210 x 70 x 20mm (8.2 x 2.7 x 0.7")
  • Weight: 800g (28.2oz)
  • Abrasive: white aluminium (WA) oxide  

Care

Like many products designed for the high-end user, the Naniwa Chosera stones require more care than your average stone. Unlike some waterstones, these are not to be left in water, leaving them in water will affect the bonding. When you are done, just let them air dry. Don’t try to speed up the drying process by exposing them to heat, just let them air dry so they can dry evenly. Store the stones only after they are completely dry. If this extra care is too much for you, we suggest you choose a different type of stone.

Most of our products are handmade in Japan, and sometimes the one that you receive maybe slightly different to the photo. This is very common and in no way it will affect the performance of the product.

If you have any questions or concerns, please do feel free to let us know.
