While the product’s ad shows easy sharpening of serrated knives, Consumer Reports testers found that this wasn’t the case. If you have better-quality steel knives, don’t waste your time with the Edge of Glory. Sharpen them yourself at home or take them to a professional sharpener. If your knives are cheaper and made of softer metal, it should sharpen them up okay. Just keep it away from the steak knives and the Wusthof.
Here’s the original advertisement, for your amusement:
