Discover Atoma sharpening stones on KnifeLeader.eu! These sharpening stones are the work of Japanese manufacturer Tsuboman. Designed directly in the land of the Rising Sun, they are highly effective, top-of-the-range diamond sharpening stones. The stones consist of a thin steel plate whose surface is studded with numerous diamond abrasive particles, ideal for fast, easy sharpening. The diamond plates rest on an aluminum support with the aid of a powerful double-sided adhesive tape. This means you can easily change the diamond surface when it's no longer effective, so you don't have to buy a whole new sharpening stone. Another big advantage of the Atoma diamond stone is that it wears very slowly, making it exceptionally durable. Tsuboman Atoma stones are ideal for sharpening your Japanese knives!
