Material Description

A Magnesia partially-stabilized Zirconia with exceptional transformation toughening properties, Contains 96.5% ZrO2and HfO2 in combination with 3.5% MgO.

Designed for applications requires maximum strength.

Homacera Ceramic knives are a modern innovation applying with above materials. The hardness, strength and corrosion resistance of Zirconia (ZrO2) Ceramic provides significant advantages compared to traditional stainless steel knives: the ultra-sharp ceramic blade will hold its edge much longer than regular steel, go literally years without re-sharpening when you use these stain and rust proof knives!

Resistant to food colourings and acids which eventually discolour traditional steel knives. Ceramic knives also do not leave behind metallic tastes on the food you are preparing which is great for you and your guests. A Ceramic Knife is an environmental, friendly, chemically stable product, which is rust-free and non-corrosive. The non stick knife and handle surface is much easier to clean than steel and wood, and will not mark or absorb food colours and odours as mentioned above and they are easy to care for by simply rinsing in warm water.  Lastly, they do not need to be fully dried when stored which is great when you are in a hurry.

Ceramic Knife Care Instructions

  • Always use with a wood or plastic chopping board. Avoid stone, marble glass or tile chopping boards.
  • Ideal for vegetables, fruit and boneless meats.
  • Avoid dropping the knife on hard surfaces.
  • Do not turn the blade on its side to smash garlic or other items.
  • Hand wash with water or detergent, do not put in the dishwasher.
  • Store in a knife block, sheath or tray.
  • For discolourations clean the blade only in a mild bleach solution.
  • Avoid cutting frozen foods or bones
  • Do not try to sharpen with a conventional knife sharpener.
  • Do not twist the knife during the cutting process
  • Avoid placing objects on top of the blade as this can cause it to break and chip.
  • Please remember the blade is ceramic so it will be prone to small chips.
  • We recommend the use of the CeramiChef Knife Shield when washing and storing your knife to help prevent accidental damage.

Craftsmanship

  • Firstly, materials used high quality zirconia sand from Australia.
  • Secondly, after 36 procedures craftsman manufacture Process, we make zirconia as 3Y ceramic materials. Homacera uses this special material to ensure the best quality and performance.
  • Thirdly, after 300 tons second time vacuum and high pressure molding, fine sands materials are made into the cutter blank, while the ready piece at the beginning is very fragile, easy to be broken. Thus we need to put them into the 1700 degree high temperature furnace to fire 120 hours continuously.
  • Fourthly, the fired cutter blank, rigidity can reach 8.5 classes, only less than 10 classes diamond, even throw from the second floor, it is excellent without damage.
  • Fifthly, the ready cutter blank, go through Germany advanced technology equipment, with the care and precision of a sculptor, the blade is sharp unparalleled and wear well.
  • Finally, with another 7 procedures quality inspection, Homacera fine ceramic knives, win a lot customers’ love by its excellent function and quality.

Sharpening Advise

Using Diamond sharpener
  1. Place the diamond sharpener on a flat stable surface like a table or kitchen counter.
  2. Hold the diamond sharpener in place as you insert the heel of the knife into the sharpening groove. Pull the knife backwards toward your body as you press it lightly into the groove.
  3. Repeat this process 5 to 7 times for each knife you intend to sharpen. Use lighter and lighter pressure on the knife for each pass through the sharpener.
  4. Wipe the length of the ceramic knife blade clean with a slightly damp kitchen towel. This step helps to remove the ceramic dust that is generated during the sharpening process.
Using Silicon carbide wheel or stone
  1. Purchase a silicon carbide wheel or stone to sharpen your ceramic knives–if you don’t want to use a diamond stone. Silicon carbide stones are made of a softer aluminum oxide and may not be as abrasive. If your diamond blade leaves any scratches, the silicon carbide wheel will remove any fine scratches left by the diamond blade.
  2. Follow the same steps for the diamond sharpening stone in order to obtain a sharp edge on your knife.
Tips & Warnings
  • Never wash ceramic knives in a dishwasher.
  • Do not attempt to operate a sharpening wheel unless you are well-versed in its use. Injuries can result from knives that are broken or dropped on the spinning sharpening wheel.
