Atoma Tsuboman Diamond Sharpening Replacement Plate #1200

The Atoma Tsuboman Diamond Sharpening Plate #1200 is a replacement abrasive surface designed for mounting on an Atoma aluminum base. The #1200 grit is intended for routine sharpening and edge refinement, offering an excellent balance between cutting performance and edge quality.

Its working surface is coated with high-quality diamond abrasive particles arranged in Tsuboman's distinctive pattern. This design promotes efficient swarf removal, consistent cutting action, and long-term abrasive performance. Unlike traditional waterstones, the plate maintains its flatness throughout use and does not require resurfacing.

#1200 grit is ideal for refining an edge after coarse and medium sharpening stages. It produces a cleaner and more controlled edge structure while preparing the blade for further finishing on higher grit abrasives. For many kitchen and workshop applications, it can also serve as a practical finishing stage on its own.

The diamond abrasive performs efficiently on carbon steels, stainless steels, and advanced powder metallurgy steels with high wear resistance. It handles demanding steels such as ZDP-189, HAP-40, and SG2/R2 with ease, providing fast and consistent sharpening performance.

As a replaceable abrasive component, the plate allows users to refresh their Atoma sharpening system without replacing the aluminum base. This makes it a practical and economical solution for those seeking long-term performance, durability, and repeatable sharpening results.
