Although the duration of sharpening is much longer than that of a stainless steel knife, if the knife has intensive use, it may be time for you to consider sharpening it. Here we will talk about the ceramic knives that are the best quality reference of their kind available on the market.

You want to know how to sharpen ceramic knives,  right? Well, here we will explain the options you have since its greatest difficulty is the strength of its high-performance zirconium oxide  ceramic blade developed by the Japanese Kyocera.

If you have a ceramic knife at home, you know that you have a very light tool that allows you to work for a long time without hardly feeling its weight in your hand. These knives, which at first seem very fragile, are not at all (just don’t drop them or use them to make large levers when you are cutting, for example, a zucchini).

We can work with a wide variety of foods, mainly vegetables and fruits, but we can also use it to fillet and work with meat in general. These knives keep their sharp edges much longer than a knife with a stainless steel blade. The only consideration is that we must maintain the edge with a suitable tool, we will not be able to use, for example, sharpening stones since we can damage the blade.

Let’s go by steps, we will explain all the alternatives: from sharpening it at home to taking it to professional sharpeners.

Kyocera has released an electric sharpener that allows you to sharpen your knives effortlessly. This electric sharpener has diamond stones (a material that is harder than the knife blade) and in this way it is possible to create an effective and long-lasting sharpening.

Ceramic knives cannot be sharpened with a water stone or manual sharpeners unlike those made of steel. Ceramic, although it is a material without pores and extremely hard, is fragile by nature, so we must use a sharpener that treats the blade properly.

One of the most common problems that ceramic knives have is that if we are careless due to a blow or misuse, the blade appears dented or irregular. With an appropriate sharpener, we can correct these irregularities and restore the knife as the first day. Yes, we will lose some material during the process, but this will be more than compensated when we recover its cutting properties, even if the blade is smaller.

Kyocera DS 50 electric sharpener for ceramic and stainless steel knives.

Going into detail in the Kyocera electric sharpener , we see that it has two diamond stone grinding wheels: one for a first coarse sharpening pass and another for a final polishing of the blade or fine sharpening . You have to repeat the past of the sheet several times to achieve an optimal final result.

You can also use this sharpener for steel, stainless steel or titanium knives . This Kyocera sharpening machine is perfect for keeping knives sharp at home, its operation is very easy and does not require maintenance. It uses two common AAA batteries.

Ceramic knives retain their edge for much longer than a steel knife, so their maintenance is more sporadic. The cutting capacity is truly exceptional and as they have a small size they are very agile in the hand . Ideal for working with pieces of fruit and vegetables since the cut is so clean that it does not crush the vegetable fibers and retards oxidation for much longer, keeping the vegetable fresh.
