Professional Quality
Shapton is serious about calling these Professional stones. Hard working professional sharpeners need stones that they can rely on. Stones that sharpen fast and well without wasting time. The Kuromaku Professional stones do just that.

• Splash and Go - The Kuromaku stones do not absorb water like many other water stones do. This means that there is no soaking required prior to using them. Get them wet, and start sharpening. No time spent waiting for them to saturate.
• Fast Cutting - Kuromaku Professional stones sharpen fast. In our tests, they are among the fasting cutting of water stones. Whether you are sharpening for yourself or for a customer, they are perfect for getting an edge sharp, and getting it back to work.
• Hard Wearing - No one likes the time spent flattening water stones, and while the Kuromaku Professionals do need to be flattened, they require less flattening less often than inferior quality stones, saving valuable time for the professional or serious home sharpener.

Ceramic Abrasives
The Kuromaku Professionals are made using very accurately graded ceramic abrasives. The ceramic abrasives make for stones that cut fast at every grit level. The tight-tolerance sorting of the abrasives results in a wider range of grits than most other brands. Ten distinct stones span the range of extremely aggressive 120 grit all the way to incredibly fine 30,000 grit. A range that insures you will find just the right combination for your sharpening demands.
