Ceramic knives are a great choice for the kitchen as they are incredibly sharp and lightweight. However, because ceramic is brittle, it can chip easily and must be sharpened more frequently than other knives. You can sharpen ceremic knives with an electric knife sharpener, dimond stone or a dimond file. Sharpening ceramic blades is easy and doesn’t require expensive tools.
Can You Sharpen A Ceramic Knife?
Yes, it is possible to sharpen a ceramic kitchen knife. However, sharpening a ceramic blade requires special care and attention as the material is extremely brittle and can easily be damaged or broken if not handled properly.
Why Do Ceramic Knives Need Sharpening?
Ceramic knives are made from a hard material called zirconia, which is second only to diamonds. This allows them to maintain their sharp edges longer than their steel counterparts. However, they aren’t immune to wear and tear; over time, the edges may become dull, which can negatively impact their cutting performance.
How To Sharpen Ceramic Kitchen Knives?
Method One – Electric Knife Sharpener
This method is best for those who want a simple and quick process. An electric knife sharpener can easily sharpen ceramic knives with the help of rotating grinding wheels.
Step 1. Make sure to use an electric knife sharpener specifically designed for ceramic knives, as other tools or methods can cause damage to the blade.
Step 2. Turn on the sharpener to a light setting before starting.
Step 3. Press gently with the knife in the sharpener at a 10-15 degree angle.
Step 4. Sharpen only one side of the blade and stop for a few seconds when you hear a beep or the knife passes through the sharpener.
Step 5. Test on a soft item, such as tomato skin, to check if it cuts cleanly before switching to another side of the blade.
Step 6. If not satisfied with the sharpness or the edge, repeat steps 3-5.
Step 7. When finished, turn off the sharpener and clean the blade with a damp cloth to remove any dust particles before storing it safely in a kitchen drawer.
Method Two – Using A Diamond Stone[/su_heading]
Step 1. Start with a coarse diamond stone (400 or 600 grit) to sharpen your ceramic knives. You must select the correct grit for the job–if it is too coarse, it will damage the blade and if it is too fine, it won’t be effective at sharpening.
Step 2. Place the stone on a flat surface and wet it with water before you begin. Ensure your hands are dry, as moisture can interfere with sharpening.
Step 3. Hold the knife at an angle of 20 degrees to the stone and begin moving it back and forth in a circular motion, maintaining the angle throughout the process.
Step 4. After a few passes, stop and check to see if you’ve achieved a sharp edge. If not, repeat the process until it is sharpened to your satisfaction.
Step 5. When the blade is sufficiently sharp, use a finer diamond stone (800 or 1000 grit) to smooth out any rough edges or burrs that may have been created.
Step 6. Finish the sharpening process by wiping any water or oil residue on the blade with a soft cloth.
Method Three-Using A Diamond File
Step 1: Start by firmly holding the handle of your ceramic knife in one hand and the diamond file in the other.
Step 2: Run the diamond file along the length of each side of the blade several times. You should do this at a 45-degree angle to remove an equal amount from both sides.
Step 3: Use light pressure and keep the diamond file consistent along one line to avoid uneven sharpening.
Step 4: Once you’ve done this for a few minutes on each side, check your progress by gently running your finger over the blade’s edge. If you can feel a smooth surface, then it means that you have achieved the desired sharpness.
Step 5: If not, repeat the process for a few more minutes before checking.
Step 6: When finished, thoroughly wash and dry your knife to remove any residue from the filing process.
Alternative Method – Take It To A Professional
The other option for sharpening your ceramic knives is to take them to a professional. A professional can use their expertise and special tools to sharpen the blade more accurately and safely than you can at home. They may even be able to provide additional services such as honing, polishing, and balancing the knife. This method is the most reliable but can also be the costliest.
Whichever method you choose for sharpening your ceramic knife, make sure that you take all necessary safety precautions. This type of knife should always be handled carefully and cautiously, so pay close attention to what you’re doing and follow all instructions.
