The Atoma Diamond Plate line is one of our most popular alternatives to water stones amongst our sharpening aficionados. This line consists of an aluminum base plate and a diamond impregnated sharpening pad. The diamonds are arranged on the pad in a dot pattern, allowing for a much more consistent and even scratch pattern on the knife edge. The diamond plates are an excellent alternative to powered devices such as grinding wheels or sanding belts, due to the reduced heat build-up. This 600 grit plate is cut to fit the Edge Pro. These plates are excellent for wear-resistant metals like ZDP-189 or M390. They are even great for keeping your other Edge Pro water stones flat. The layout of the diamonds keeps the plate from sticking to the stone during the flattening process.
I’ve been using the 400 and 600 grit Atoma plates for all my EDC knives. I use the 400 to remove any minor nicks,and finish with the 600 using very light strokes to avoid a burr. It leaves a nice aggressive toothy edge that has great edge retention. These stones are a bit pricey but consider that you’ll never have to flatten them and since they’re all the same thickness and will never change thickness,you will get consistent angles on your EP without having to use a stop collar/marker/angle cube when switching stones. I originally bought all the lower end Shapton glass stones,but wish I had bought all the Atomas up to 1200,and then bought the 2k and up Shapton stones. The 140 Atoma plate is all you’ll ever need for fast reprofiling,even on the hardest wear resistant steels.
