Review on 💎 Diamond Sharpening Stones Sharpener: Enhancing Your Blade's Cutting Power with SATC by Mario Beckwith

I have contacted the seller with no response so here is my review. zero stars. "Stone" became smooth on both sides (Scandinavian sharpening) after the third MoraKnife stainless steel I sharpened with it. As you can see from the photos, it's not exactly flat, and each knife has about 1/4 inch unsharpened. (As seen in the photo.) The third MoraKnife I "sharpened," the "stone" went bare on the side of 400, so I flipped it to try and sharpen it at 1000 quit and the same thing happened. So on this particular knife. I needed this knife to be sharp, so I had to try and sharpen it with 1/4" on the sides to be able to work quickly. (This looks like a 1/2 A88 job because that's all is what I might do with the rest of the grit.) As you can see I have to reuse all three knives.Study the photos carefully and draw your own conclusions.
