ONYX COOKWARE™ knives do not become dull when washed in the dishwasher!

Coatings can wear off or fade over time, but this does not happen with our alloy, which we refer to as an alloy instead of a coating, as it is bonded to the steel at an atomic level.

The titanium alloy provides an extra hard and wear-resistant surface, so you don't have to worry about putting them in the dishwasher. The only thing you should be aware of is that the knives should not come into contact with loose objects that could damage your knife during washing. It may be a good idea to polish the knife after washing to maintain its beautiful finish.

The knife sharpener works best for ONYX COOKWARE™ knives, which have a hardness of HRC 64. The knife should be held straight when sharpening it in the knife sharpener.

The knife is sharpened if there are irregularities in the blade and it needs a clean and sharp edge again.

It is important to clean the knife before sharpening, place the knife sharpener on a flat surface, and gently run the knife through the sharpener. It is important to note that the knife should not be pressed or forced down when running it through the sharpener. The sharpener does the work for you. All you need to do is place the knife in the opening and pull it through.


Regarding the different openings on the knife sharpener, it is not always necessary to use all of them every time. The different openings have different functions:

Opening 1: For restoring and repairing dents and nicks in the blade.

Opening 2: Sharpening and shaping the blade.

Opening 3: Polishing and smoothing out irregularities in the blade.


Remember to clean the knife after sharpening.
