Suehiro Japanese Whetstones

The #320 grit Cerax Whetstone is classed as a Medium-Coarse grade stone.

The 404 variant is 50mm thick vs the 401 variant at 29mm, the 404 will give you longer life if maintained well.

A #320 grit stone has become a staple for many sharpeners due to ability to remove metal quickly and cleanly.

It will allow you to remove deep imperfections along the bevel and set the stage for the #1000 Cerax

This stone works best after the Atoma #140 Diamond plate.

#320 Grit medium finishing and well balanced whetstone with a rubber frame to remove the deep scars and smoothen the surface so that the blade becomes sharper and stain-resistant. Suitable for final sharpening of chisels, planes, steel knives, and longer blades.

The Cerax Waterstone by Suehiro Niigata Japan is renowned for its fast cutting surface, its longevity and a reputation for consistency and high quality.

These stones hold their shape well and still cut quickly enough to create a burr in a reasonable number of strokes.

The Cerax Stones do require soaking, however they're not extremely thirsty. A soak for only a few minutes and they're ready to go. An occasional splash of water during use keeps them working smoothly. They should not be stored in water.

Cerax is packaged with a small Nagura stone, which is used for unclogging the stone if particle material becomes embedded during the sharpening process.
