Our knife sharpener is ideal for our ONYX COOKWARE™ knives with a hardness of HRC 64, as well as our latest addition – stainless steel knives made of 5Cr15MoV steel with a hardness of HRC 58. This type of knife is easy to sharpen, even for beginners, and is perfect for both new knife owners and those who want to learn how to sharpen their own knives.

For optimal sharpening, it is important to keep the knife straight and stable during sharpening. If there are irregularities in the blade or if a sharp edge needs to be restored, it is time to sharpen the knife again.

Before sharpening, it is important to clean the knife thoroughly. Then, place the knife sharpener on a flat surface and gently guide the knife through. Avoid pressing or forcing the knife down into the sharpener; instead, let the sharpener do the work while you smoothly guide the knife through the slot. The knife sharpener is suitable for all knives.
