New Technology, Old-world Craftsmanship

ViCera™ ceramic knives are made of an advanced, high-tech ceramic called zirconium oxide (also known as zirconia). Zirconium oxide is extremely hard and wear resistant, rating 8.5 on the Mohs scale - surpassing stainless steel (5-6 Mohs) and approaching the hardness of diamond (10 Mohs). The Mohs scale, developed by mineralogist Friedrich Mohs, is the universally accepted standard for measuring the hardness of minerals.

During production, our master craftsmen fashion the pure zirconium oxide into knife shaped blanks using high-pressure presses. The finished blanks are then hardened in a process called "sintering", which requires special kilns that can achieve temperatures of over 1000 degrees Celsius. After they are removed from the kilns, the knives are cooled to a naturally brilliant white and then hand-sharpened on a special diamond coated grinding wheel.

When you pick up a ViCera™ ceramic knife, you are holding a perfect balance of new technology and old-world craftsmanship. A brilliant, white blade that is as light as a feather and tougher than nails.

  • Usage

    Take care when using this knife as the blade edge is extremely sharp.

    This knife is used for cutting foodstuffs only. It should not be used for any other purpose such as smashing garlic or any other items by turning the blade on its side.

    Ceramic is not able to withstand shock. If dropped from a height the blade is liable to break.

    Always use a plastic or wood cutting board to protect the edge.

    Do not attempt to cut hard ojects such as bones, frozen food, metal, glass, or earthenware. Do not attempt to cut corn or hard thickened items such as pumpkins. Doing so may cause the blade to chip or crack.

    Do not expose to flames.

    Keep out of reach of children.

    In time, tiny chips may appear on the blades edge. This happens to all ceramic knives and does not affect the knife's cutting ability.
