The Atoma Diamond Plate Kit is an excellent choice for repairing chipped knives and flattening whetstones, while providing a beautiful finish on your tools. These diamond plates offer the advantage of maintaining a flat surface and extended durability compared to traditional whetstones.

To use the plates, mount your whetstone in a stone holder and rub the Atoma plate on top of the whetstone in various directions until the stone is effectively lapped.

Atoma Diamond plates can be used dry or with water, depending on personal preference.

Atoma Diamond Sharpening Plates are products of Tsuboman, a superb Japanese manufacturer renowned for their refined diamond products. These plates are made of mono-crystalline diamonds with a cutting abrasive surface mounted on a 10mm thick stainless steel base. The base is machined to be extremely flat, ensuring the diamond plate remains flat throughout its use.

The quality and durability of Atoma plates are among the highest available on the market. They feature precision-made surfaces with high uniformity, maintaining their flatness even after prolonged sharpening sessions. The diamond plate can be replaced after a few years without purchasing another baseplate, as they are adhered using strong double-sided tape.
