With the right care, ceramic knives can keep sharp longer than steel knives. However, the brittleness of the material means they are more prone to chipping, and even with the right care, they will dull over time. Having them professionally sharpened is the only option to bring the perfect edge back.
You'll Have a Hard Time Sharpening Ceramic Knives
They also tend to stay sharper than metal kitchen knives. However, as with all blades there comes a time when they lose their precision as they yield to bluntness. And when that time comes, a ceramic blade can only be sharpened using a diamond sharpener.
Breaks easily - One disadvantage to ceramic blades is that they are brittle, which means they chip or break more easily than stainless-steel blades. This is especially true with ceramic blades used for industrial purposes.
Unlike stainless steel knives, which need sharpening approximately one a year, ceramic knives can go five to seven years between sharpenings. Because the ceramic knife is so hard, it requires a diamond sharpening stone.
Because it is naturally so hard, it doesn't need to be sharpened as much as steel in order to cut materials and have a useful shelf life – but it does need to be sharpened in the right way in order to be safer than steel blades.
Remember that ceramic blades will need just as much oil, or more oil than steel blades. I know most of you don't have any problems with ceramic blades, but I also know many have nothing but problems with them. So maybe this information can help some of you prevent these problems your having.
Wood and plastic cutting boards are the best match for ceramic knives. A new material used to manufacture cutting boards was introduced in the beginning of the 21st century – compressed wood fibers. This natural element does not absorb the materials it comes into contact with, especially water.
Unfortunately , a knife that is not detectable with a metal detector is illegal in California. That would make the ceramic blade illegal.
Make sure that you're using an automatic diamond knife sharpener, which manufacturers design specifically for ceramic knives. Place the knife-edge in the slot in the sharpener, then pull your knife through it from heel to tip.
Fragility is the major disadvantage of ceramic materials with very high requirements for transportation and installation. Ceramic works can be easily broken when being collided by hard objects.
Also, I said "typically" regarding the blade having no metal in it because the truth is that some (perhaps not all) ceramic knife manufacturers DO put a small amount of metal in their ceramic blades (just enough to set off metal detectors) because they understand the risk in a knife (that is actually ALL ceramic as ...
The biggest concern with ceramic knives is the chipping of the blade. The miniscule pieces breaking off of the blade shows how fragile the knives are, and demonstrates that the sharpness will decline.
The more knives rub against other tools, the more their blades will dull. This means just opening and closing a drawer can do damage over time. Either keep your knives in individual sheaves to protect them inside the drawer, or invest in a safe storage solution like a knife block or magnetic knife strip.

Here's the TLDR: Use end-grain walnut, cherry, or maple wood—they're the best for your knives. Outside the wood family, use plastic, and synthetic rubber boards.
While ceramic knives may need less sharpening than their steel counterparts, when the time does come to have them sharpened, it is a far more complicated process.
Never cut on glass, ceramic or countertops. Those surfaces are harder than a knife's edge and will quickly dull the blade. It's what you cut on that dulls knives, not what you're cutting.

Ramsay likes Henckels knives. This is a German brand known for their toughness and bulky blades.
There's a few ways to sharpen a ceramic knife. You can use a honing rod, which is a long, thin rod made of steel or diamond that you run the blade of the knife against to sharpen it.
Ceramic is such a hard material it can only be sharpened by diamond.
Ceramic blade knives - specifics
They do not oxidize fruits and vegetables: the inside of an apple will remain white longer when cut with a ceramic knife; lettuce won't turn brown either!
The chipping size of 10 mm or less at the tip and 3 mm or less on the blade edge may be repaired. For details please click here. If the ceramic knife is broken, what should I do? It is dangerous to use as is and may cause injury.
