  1. Hello

    I read all of this content. this is the post that shows clearly how to sharpen ceramic knives. I have bought a ceramic knife and i looking for a way to sharp my ceramic knife. This content helps me more to sharpen my knife. All the sharpen methods are effective. I enjoyed and love those methods. Thanks!

  2. It seems everybody is claiming that ceramic knives can be made sharper than steel knives, and stay sharp longer. I bought my first cyanic knife a few weeks ago, and have found the opposite to be true. It wasn’t what I consider especially sharp when it was new, and when I sharpen it, it dulls quickly. I am not at all impressed. Maybe I bought a cheap one, but a steel knife at the same price point would be better- if you know your knife steels.
