SUEHIRO Flattening Stone #100

Suehiro coarse #100 flattening stone.

Whetstones wear unevenly on the surface when used, as the sharpening movements mostly eat away at the central part of the whetstone. The best way to notice the curvature of the surface is to draw a grid on the stone's surface with a pencil (vertical/horizontal lines), then grind the surface with the flattening stone until the entire grid has disappeared from view. Harder stones, such as the Shapton Glass series, will remain in good condition without flattening for much longer than other stones; but even these require regular flattening. Again, the use of a flattening stone ensures the best results.
