About the Brand

The Mizuyama stone is Korin’s original line of sharpening stones that gained popularity over the years for its quality. The stone was developed by a natural sharpening stone specialist, Mr. Sugai and his grand master, Mr. Mizuyama, over 5 years ago. The Mizuyama stones are high quality tools that are made for and used by professional sharpeners. These stones absorb water to create a nice slurry of mud that makes the sharpening process easier and faster. Mr. Sugai and his apprentice uses these stones everyday to sharpen and repair knives as well as teach customers proper sharpening methods.

Benefits of a #3000 Grit Stone

  • When sharpening knives, it is important to use medium stones and finishing stone. However, it is easier to use a #3,000 grit stone as a buffer in between, rather than jumping from a #1,000 grit stone to a #6,000 grit stone. 
  • Cutting oily ingredients leads to shorter edge retention. According to Mr. Sugai, one of the uses of the honing steels is to help take the oil off knives. If you are planning to cut meat such as chicken, it is best to stop at the #3,000 grit stone. Although, the #6,000 grit stone will give you a more refined edge, it will also be more prone to dulling faster. Using a rougher edge will maintain the blade for longer. 
  • Best finishing stones for boning knives.

Due to the humidity difference in Japan to the US, the #3000 grit stone may crack after some use.

Wet the surface of the Mizuyama fine stone and use.


  • Please do not soak finishing stones (#3000 and above). Soaking a finishing stone will result in the stone cracking and breaking.
  • Returning a stone into a box while still wet or damp will result in molding and decreasing quality.
  • For double sided stone, please only soak the medium stone side (#1000). Failure to do so will result in the stone splitting and or breaking.
