• This double-sided electroplated diamond flattening stone uses durable diamond abrasive to quickly restore uneven or dished whetstone surfaces.

    It is particularly effective on harder, non-soaking whetstones and stones that are prone to loading, including Suehiro’s Gokumyo, Kouseki, and DEBADO series. It can be used to flatten a wide range of whetstones, from coarse stones to fine finishing stones.

    Use the coarse #150 diamond surface to quickly restore a flat surface, then finish with the #500 diamond surface to create a smooth and optimal sharpening surface.

    The included plastic storage case can also be used as a convenient handle during use.
