To keep your ceramic knife in top shape, all you need to do is follow a few guidelines. Ceramic knives are resistant to acids, oils, salts, and will never rust. Moreover, they can last up to 10 times longer than steel knives before they have to be resharpened. However, damaging a ceramic knife is easier than you might think, so keep the following in mind:
While your ceramic knife’s sharpness can last for years, you’ll have to sharpen it eventually. Before we get into that, let me clarify something first: honing is not the same as sharpening. Honing refers to realigning the microscopic serrations in the edge of the knife, using a tool called a honing rod. Bear in mind that ceramic knives do not need to be honed.
To sharpen your Kyocera ceramic knife, you will need to either send it to Kyocera (you just have to pay for the shipping fee) and it will be resharpened for you, or you can buy the Kyocera ceramic knife sharpener and sharpen it yourself. Use a knife sharpener for ceramic knives, the ones for steel knives won’t work.
This is the easiest part. Since the blade is non-porous it won’t absorb any food element. Just wash it by hand with a regular detergent and wipe it with a kitchen towel.
Washing your ceramic knife in a dishwasher is not recommended. The rattling motion against other objects can result in a chipped knife or a damaged object. Furthermore, if your knife has a wooden handle it can be damaged as well. Finally, since ceramic blades are so sharp, you run the risk of cutting yourself if you forget about the knife and reach into the dishwasher.
The best place to store your ceramic knife is either a knife block or a knife tray. You can also keep it in its package.
Things to avoid
- Dropping your knife. You can chip the blade if it hits a hard surface from a certain angle.
- Cut into hard materials such as bone and frozen food. It’s safer to cut into soft foods.
- Prying or twisting. The blade can break if you do this.
- Slicing cheese. A dense cheese will require a significant effort to slice, which might lead to a broken blade.
- Using the side of the blade to smash garlic or the like. This can damage your blade as well.
- Cutting on hard surfaces such as marble, stone, glass and plates. Use cutting boards made of plastic or wood instead.
That’s all there is to it. With the proper care, your ceramic knife will last you a lifetime.
