The Atoma Diamond Plate with Handle is a professional-grade diamond sharpening plate by Tsuboman, upgraded with an ergonomically designed handle.

Benefits of the handle:

• Improved stability: The secure grip prevents slipping during flattening and ensures even pressure distribution.

• Enhanced safety: Keeps hands away from water and the stone surface, reducing the risk of cuts or accidents.

• Greater efficiency: Less fatigue during extended flattening sessions, making it ideal for professional use.

• Professional reliability: Perfect for chefs and sharpeners who regularly maintain larger whetstones.

Although it comes at a higher cost compared to the standard model, the added stability, safety, and efficiency make it a worthwhile investment for serious users.
