Review on Durable Atoma Diamond Sharpening Flattening Whetstone for Efficient Blade Polishing by Phil Kowal

Use as a lapping plate. Works well for the price, while there are definitely pricier options that perform better for significantly more power. You get what you paid for the situation. The longevity lasts for several months with light sanding in work kitchens. Cuts quickly to straighten the bars. Use a thinner Nagura and you will reduce the scratches from the diamond plate. The atom does not compensate in any way, neither shape nor form. Many Thanks
