Japanese Water Stones, What They Are And What We Have

What are Japanese Water Stones?


We carry a wide selection of Japanese water stones.

Historically, Japan was famous for its natural sharpening stones. That tradition of quality sharpening stones continues today with the synthetic stones produced in Japan. We will look into the general features of these man-stones, what makes them popular and the products we carry from some of Japan's best stone manufacturers.

Japanese water stones are generally softer than other sharpening stones and are used with water. They are known for sharpening quickly and producing highly refined edges. Users of Japanese knives or woodworking tools find them a natural fit for sharpening. Their ability to cut fast and polish well has led to Japanese water stones being widely embraced by sharpeners of all tools and knives.


Water stones develop a slurry in use.

When water stones break down, they expose fresh abrasive particles that promote fast cutting and reduce clogging of the stone. The slurry created is effective at creating a polish when using fine stones.

Because of the faster wear rate, water stones should be regularly resurfaced to keep them flat. Flattening a water stone is easily accomplished with a Flattening Stone.


See our article How To Flatten A Water Stone for more information.

Broadly speaking, there are two main types of water stones: Soaking and Splash and Go. Soaking stones need to be submerged in water until saturated before use. Splash and Go stones only need some water to be applied to their surface. Splash and Go stones are considered desirable because of the convenience of not having to soak them before use.
