Naniwa Chosera #600 grit

The Naniwa Chosera series, crafted exclusively for the Japanese market, offers premium sharpening performance. Featuring a thicker design than the PRO line, this whetstone includes a Nagura flattening stone for enhanced sharpening efficiency, with base attached. Built for professional-grade use.

This is a coarse stone. Use this stone to repair chips or reshape an edge.
If you haven't sharpened your knife in months, then start here.

Recommend progression: 400 grit --> 1000 grit --> 5000 grit
optional 10,000 grit 

Care Instructions
Use the included Nagura (included) before/after use.
Only a short soak in water in needed. Do not leave in water for extended periods.
Flatten, clean and allow to air dry in a cool place. Allow to completely dry before storing.

Nagura stone: The Nagura Stone is used to help maintain flatness of the surface.
The Nagura also helps to make a slurry prior to sharpening, which speeds up the sharpening process.

Leigh’s 2 cents:
Massive, high-quality whetstones! Made to sharpen many knives.
The base is attached and does NOT fit into a stone holder (nor do you need one).
Get the sink bridge to match and/or a Atoma flattening plate.
Optional 10,000 grit if you really want to spoil yourself :-)
