Diamond is the hardest material in the world, and it also has abrasive power when properly shaped. Atoma diamond stones are made by electro-welding laboratory-produced diamonds to a steel plate, ensuring that they are properly positioned and stay in place. This technology is widely used in the stone cutting business, but recently it has also been widely used in the knife sharpening business.

Grit #400 is the universal Atome grit, quite suitable for both straightening and sharpening stones. The extremely fine diamonds with their sharp edges remove even the hardest materials without any problems. That's why this is one of the favorite sharpening tools when sharpening knives made from high carbon steels, hardened to over 60HRC. This graining is recommended if you have kitchen knives of the mentioned performance and is considered ideal or even necessary for sharpening pocket, hunting and other folding and smaller blades that are made of extremely hard steel.

In addition to sharpening, the most important role of the Diamond Stone Atom is to straighten other sharpening stones. Due to the technology itself, the Atom is impossible to deform and it always remains absolutely straight, making it ideal for straightening ceramic sharpening stones. As with steel, the sharp edges of the diamond cut the ceramic stone with ease, conveying the flatness of the Atom, leaving a perfect sharpening surface.

Atoma diamond stones are produced by the renowned Japanese abrasive manufacturer Tsuboman. Top quality mono-crystalline diamonds are first welded to a stainless steel plate which is then mounted on a second, 10mm thick aluminum plate which is machined to be absolutely flat. This construction ensures that the Atoma will not deform even a little over time and gives the product massiveness and ease of use.

Dimensions: 210mm x 75mm x 11mm

Material: Diamond, stainless steel, aluminum

How to use for sharpening knives: When you want to sharpen a knife at atom, it is extremely important to use the right technique, to ensure that this product serves you adequately and for a long time. First place the atom in a stone holder or other secured non-slip surface. Then place the blade of the knife against the surface of the stone and move the blade over the surface of the stone very gently, almost without pressure. Let the diamonds do the work for you. You can use any technique, but it is very important to use as little pressure as possible, otherwise the diamonds may fall off the plate and permanently slow down your Atom. We recommend that you use the entire surface of the stone evenly.

How to use it for straightening stones: Atoma is the perfect tool for straightening other stones and using it for this purpose is extremely simple. If necessary, before straightening, soak your stone in water for about 10 minutes, as you would before sharpening. Splash&Go stones do not need to be submerged. Then place the stone on the sharpening holder and place the Atom over it so that the diamonds are facing the stone. Rub Atoma on the stone with light movements up and down, without much pressure, and in just a few seconds your stone will be absolutely flat again.
