These diamond sharpening stones combine durability, precision and efficiency, making them ideal for knives, tools and even as lapping stones.

Atoma stones are versatile and reliable, perfect for any sharpening enthusiast.

Atoma Diamond Stones: reasons to choose this brand
Unique cluster structure
Atoma Diamond Stones' diamond abrasive particles are placed in clusters, creating a distinctive sharpening experience. This approach ensures optimum results while reducing the risk of damage to the stone. Still, even with these sharpening stones, a bit of care is required. Do not put too much pressure, but let the abrasive particles do their work. Thanks to the space between the clusters, slurry is efficiently disposed of, so the stone does not accumulate and remains effective for a long time. This makes Atoma unique compared to traditional diamond sharpening stones.
Durable and affordable design
The construction of Atoma Diamond Stones makes them not only durable but also economical. The diamond clusters are attached to a thin steel plate glued to an aluminium base. This lowers production costs without compromising on performance. Moreover, Atoma offers replacement top layers, so you only need to replace the abrasive surface in case of wear, which is a cost-saving and sustainable solution.
Multi-functional
Atoma Diamond Stones are versatile. Besides sharpening knives and tools, they are also used as levelling stones to make bonded and natural sharpening stones flat again. Thanks to the different grit sizes offered by Atoma, you can re-grind any bonded sharpening stone evenly, without causing deep scratches. With Atoma, you combine a high-quality sharpening stone with the benefits of a lapping stone, making your sharpening even more efficient.
Why use the Atoma Diamond Stones?
Atoma sharpening stones are available in various grit sizes, most of them relatively coarse. As a result, you mainly use them for repairing damage before sharpening your knife properly with finer grit sizes. The very coarse 140-grit stone is still lower than a 100-grit bonded Japanese sharpening stone in terms of grit size. The finest 1200 grit Atoma stone is roughly comparable to a 1000 grit bonded Japanese stone.
Thanks to their versatility, Atoma stones are used not only for knives and tools, but also as lapping stones to make other sharpening stones perfectly level. Thanks to their durable design, with replaceable top layers, they offer a cost-effective solution ideal for professionals and enthusiasts alike. Atoma stones are more than a sharpening stone; they are a symbol of Japanese innovation and craftsmanship.
Atoma Diamond Stone: lapping stone and sharpening stone in one
Because Atoma stones are so flat and wear-resistant, fans have discovered they also make some pretty great lapping stones. You use these to make your bonded sharpening stone or natural sharpening stone flat again after use. Indeed, compared to other diamond surface stones, these Atoma stones are quite an inexpensive option for this purpose. Especially since you can use them as a regular sharpening stone too.
