Not Even Close To Factory Sharp
on September 14, 2014
I received this as a gift and was very excited by the idea that I could return my awesome Kyocera chef knife back to its original sharpness. However, it has turned out to be a big disappointment... and not just because this thing eats through batteries like an '80s boom box.
If you're planning to use this on a cheap ceramic knife, you'll probably be happy with it. A knife sharpened with this will be sharp enough to use and will definitely cut things.
However, if you've purchased a Kyocera knife before you're probably very familiar with how incredibly sharp they are when factory sharpened. Do not be fooled - This product will NOT get your good ceramic knives anywhere near as sharp as when you bought them. When I compared the knife I sharpened to a new Kyocera knife that I had just taken out of the box (another Xmas gift), the difference was extremely noticeable. The old knife cut through a tomato with a bit of pressure; the new one sliced through like that tough skin wasn't even there.
After my cast iron pan, my knives are probably my most used cooking tools. For my money, I'm a lot happier sending my knife to the factory every couple of years and returning it to that insanely sharp, long lasting edge that makes me smile every time I chop some vegetables.
