The Atoma Tsuboman Diamond Sharpening Plate #600 is a replacement abrasive surface designed for use with an Atoma aluminum base. The #600 grit serves as an effective intermediate stage between coarse sharpening and finer finishing, making it well suited for routine edge maintenance and sharpening tasks.
The working surface features high-quality diamond abrasive particles arranged in Tsuboman's distinctive pattern. This design promotes efficient swarf removal, consistent cutting performance, and excellent abrasive efficiency. The result is fast material removal combined with a high level of control during sharpening.
The #600 grit is ideal for restoring and refining edges that no longer require aggressive repair work. It efficiently removes scratches left by coarser abrasives and prepares the edge for subsequent sharpening on medium and finishing stones. This makes it a versatile option for both workshop and kitchen knife maintenance.
The diamond abrasive performs exceptionally well on carbon steels, stainless steels, and modern powder metallurgy steels with high wear resistance. It handles demanding steels such as ZDP-189, HAP-40, and SG2/R2 with ease, providing efficient cutting where conventional abrasives may work more slowly.
Like other components in the Atoma system, the plate maintains its flatness throughout its service life and does not require flattening. As a replaceable abrasive element, it offers a practical and cost-effective way to keep an Atoma sharpening setup performing at its best.
