Our knife sharpener is ideal for ONYX COOKWARE™ knives (HRC 64) and our stainless steel knives made of 5Cr15MoV steel (HRC 58). They are easy to sharpen – even for beginners – and perfect for both new knife owners and those who want to learn to sharpen on their own.

Knives should be sharpened at an angle of 13° on each side or an angle of 26° when sharpening both sides simultaneously.

Important things to remember:

• Clean the knife thoroughly before sharpening.
• Keep the knife straight and stable during sharpening.
• Sharpen when the blade feels uneven or loses its sharpness.
• Place the sharpener on a flat surface.
• Guide the knife smoothly without pressing – let the sharpener do the work.

The knife sharpener is suitable for all knives.
