Atoma Economy #400 Diamond Plate (by Tsuboman – Made in Japan)

The Atoma Economy #400 Diamond Plate by Tsuboman is a durable, efficient, and low-maintenance sharpening tool. Unlike traditional whetstones or ceramic stones, diamond plates do not wear down, dish, or require flattening over time. They also don’t need water for use, making them extremely convenient and easy to maintain.

Made with Tsuboman’s patented dispersion technique, the Atoma plate resists clogging and provides fast, consistent sharpening performance. The #400 grit surface is coarse enough for quick steel removal yet fine enough to refine edges and repair small chips effectively. It can also be used to flatten sharpening stones, ensuring a perfectly even surface.

Reliable, long-lasting, and fast-cutting, the Atoma Economy #400 is ideal for both professionals and home sharpeners.
