The Atoma #600 is a fantastic option for sharpeners who want a replacement for whetstones from the #500 to #800 grit range, but will last much longer than traditional whetstones.

Whetstones from this grit range are considered coarse sharpening stones, and will bring dull knives back to life, but are generally a bit softer and much faster wearing than most #1000 grit stones.

The Atoma #600 is a perfect diamond plate to get, that will give you the benefits of a coarse sharpening whetstone, but will last much longer, and will never need flattening

The main benefit of using an Atoma plate over a whetstone is its ability to remain flat and will last for an extended amount of time.

General way to use the plate is to mount the whetstone in your stone holder then rub the Atoma on top of the whetstone in various directions till the stone is lapped.

Atoma Diamond Sharpening Plates are products of the company Tsuboman, a superb Japanese manufacturer with very refined diamond products.

The Atoma plates are made of mono-crystalline diamonds with the cutting abrasive surface mounted on a stainless steel base which is 10mm thick.

It's base is machined to be extremely flat so the Diamond plate remains flat.

The quality and durability of these Atoma plates are of the highest available on the market, with precision made surfaces that have high precision uniformity. These plates remain flat after continued sharpening use.

The diamond plate can be replaced after a few years without buying another baseplate, as they are adhered using a strong double sided tape.

Atoma Diamond plates can be used dry, or with water.
