Ceramic Knives are here to stay and they are popular among chefs and home cooks alike. These knives are razor-sharp, durable, and lightweight.

Below is a review of the top 5 ceramic knife sets for home kitchen and professional use:

ABS plastic was used to make the handles and the blades stay sharp for a long time.

Kyocera knives are made to last for a lifetime. That is why each set comes with a warranty. Although it is not possible to repair the chips and cracks, Kyocera can still replace your knives if they’re damaged.

The ergonomic handles are safe and easy to grip, thanks to their grip dots and soft rubber coating. Try to avoid washing these knives in the dishwasher, though. It is better if you clean the knives manually. It is not hard to do anyway because they’re not porous. A quick rinse is all you need to do. There is no worry of rusting or odors coming from your knives either.

You’ll be happy to know that this ceramic Set is affordable and high-quality at the same time. Some people claim that these knives are not the sharpest ceramic knives on the market. But it seems like most people have had positive experiences with these knives, so you be the judge.


The popularity of these ultra-sharp ceramic kitchen knives has grown rapidly ever since these were featured in various cooking videos and word of mouth got around and now everyone is talking about the amazing sharpness and durability of these blades.

As an increasing number of people are adding these knives to their kitchen arsenal and so I also decided to jump on the bandwagon and I went ahead and ordered these sets for testing and reviewing. 


Keep reading for my pros and cons, interesting facts, comparisons to other blades and more.

Why Do I Like These Blades?

The main reason why I decided to buy a set of ceramic blades was just curiosity, as I wanted to see what was all the fuss about. I was also curious to see if the claims were true. Is it really the sharpest kitchen knife in the world?

Not only that, I did actually need a new blade. My old chef’s knife wasn’t performing all that well anymore and it had few chips and although it was stainless steel it had developed a bit of rust around the edges. As I am using my knife daily for cooking I thought I should get something that CAN really do the job and will last for a long time.

These blades are very modern looking and beautiful but that was not the main thing at all I was looking in a good kitchen knife. What I wanted was more durability and sharpness than your average stainless-steel blades would provide and most importantly, I wanted something that is resistant to acids, rust, and corrosion. I was really happy with the fact that these knives were made out of ceramic as that ensured me they won’t deteriorate any time soon.

Worlds Sharpest Ceramic Knife

So, if you are also looking to purchase a high-quality tool to add to your kitchen, or perhaps you are not that familiar with the ceramic blades then you’ll want to keep on reading so you can learn from my research and experience and hopefully, it will help you to make a more informed decision.

Below I will examine the general features of ceramic blades so that you will understand them better. This will make it easier for you to compare the various materials of these different knife sets that are available and figure out what makes one superior to another.

White blade and slick design, this knife may look like a toy at first but don't be fooled, it can do some serious chopping, slicing and dicing.

How These Super Sharp Ceramic Blades Are Made?

As the name would suggest, this knife is made from ceramic material. The more scientific name is zirconium dioxide or zirconia for short. This is a highly durable material which can make a super tough and long-lasting blade.

Zirconium Ceramic Blades

The production of these knives begins with putting zirconia powder through a dry press and then applying fire to the pressed powder. This causes the blade of the knife to form. From there, a special grinding wheel is used to grind the blade’s edges. This is what sharpens the blade to produce the actual cutting ability of the knife.

Watch this Amazing Discovery Channel video below about how these ultra-sharp blades are made and how they achieve this superior durability and firmness to make it almost as strong as diamond.

How Strong Is This Knife?

Just to give you an understanding of how hard Ceramic Blade is in comparison to some of the other well-known materials lets look at the Mohs scale of 1-10 mineral hardness. On the Mohs scale talc is listed on the bottom at number 1 and a fingernail is listed number 2. A normal metal knife blade is listed 5 and Zirconia is listed 8.5 which is just below the diamond that tops our list at number 10.

Did You Know?

Here is an interesting fact. Diamonds are no longer the hardest material in nature. Wurtzite Boron Nitride and Lonsdaleite are two known materials which are harder than diamonds.

Whenever graphite-based meteorites crash through the planet, it forms lonsdaleite. When a volcanic eruption occurs, wurtzite boron nitride is left behind. I will let you know as soon as someone starts making knives out of these materials.

Are Ceramic Knives Worth Considering?

Although I was a bit skeptical at first before I bought these knife sets, I must say it really did win me over straight away once I unpacked my first set and started slicing stuff. It was the sharpness and how comfortable and light it felt in my hand.

Also, what I have learned from talking to people and reading other peoples reviews, it turns out that people love ceramic blades for a variety of different reasons. The main reason, however, is that this cutter is ultra-sharp and has far superior durability and hardness in comparison to metal knives.

Chopping food with such ease

Once I open the box and started chopping my skepticism was gone, this was undoubtedly the sharpest knife I had ever used.

Another reason why people love these knives is, its both rust resistance and stain resistance. The sharpness of its edges will remain sharp for so much longer than the edges of metal knives. The great thing is that you’ll hardly need to sharpen these blades.

Of course, the cutting edge of the blade does eventually deteriorate and lose its sharpness. But this won’t happen for a  very long while. However, once it does happen, a special sharpening service or a diamond sharpener is needed because normal sharpeners won’t work on this super hard ceramic blade.

Lightweight yet very robust, harder and sharper than steel, this knife is perfect for #slicing, trimming, #chopping, paring, #dicing, julienning and carving plus so much more...

These knives are perfect for cutting thin slices of your favorite meats, bread, vegetables, and fruits. I think that any kitchen where some serious cooking takes place should definitely include this amazing tool to its arsenal. It does not need to be either/or, I would recommend having a good set of stainless steel blades also for the job that requires more rough cutting.

Watch this video here to see how Ceramic Knife slices foods with such ease and how it slices a pepper with such ease. It is pretty amazing.

Also, what I like about these knives is that it is lightweight, odor-free, and easy to clean. The same cannot be said for my old steel knife.

Disadvantages Of Ceramic Knives

I think I have pretty well covered all the pros and why I like ceramic knives and now you should be aware of some the disadvantages as well.

You need to treat these knives very carefully because they can easily break or chip if the blade experiences a tough blow or impact. For instance, if you drop it onto a hardwood floor or cut up vegetables on a very firm hard surface, this could damage the blade over time. Do not chop anything that is hard either, such as frozen meat or bones. Also, never use it to try and pry off the lid of some container. If you do, the tip of the blade might break off.

This might all sound bad, but take a look at the disadvantages of steel knives. For one thing, there are more pores in steel than in ceramic. That is why steel tends to trap odor and stains from various food particles it encounters. In addition, the chemical reactive nature of steel is what causes it to rust. Due to the heavy weight of steel blades, it can be tiring to chop food for extended periods of time.

A lot of people get annoyed with steel blades because they must be sharpened regularly while ceramic knives do not.

As you can see, each type of knife has its ups and downs. The final decision you make will be based on your own personal needs, desires, and preferences. The way you need to cut your food will also play a factor in your decision.

Many chefs love to select their own cookware and the material of their knives, whether it’s stainless steel or ceramic. I personally think that any good kitchen should have a set of both blades, stainless steel and also ceramic.

How To Treat And Care For Your Ceramic Knife?

Most people will clean their ceramic knives by just putting them in the dishwasher. Even though this might seem like a good solution for cleaning your kitchen tools, I would personally not recommend it for two important reasons.

Do not put sharp knives in the dishwasher.

Extremely hot water and violent motion of the dishwasher against the hard plates could damage the blades.

The first reason has to do with hot water. When you clean anything in a dishwasher, it is going to be exposed to very hot water temperatures. This kind of hot water will ruin the edge of any ceramic blade. These edges are serrated and have very thin metal strips on them. As long as those edges stay exposed to cool or normal room temperatures, then they will remain sharp and intact. But if they incur heat exposure, the edge of the blade will start to dull out because heat causes the little teeth along the edge to curl up. For this reason, only use cold or lukewarm water for cleaning your ceramic blades.

Secondly, there is a lot of water pressure inside of a dishwasher which aggressively cycles the water through all the knives and dishes. If the edge of a ceramic knife were to take a direct hit and bang against another dish or a utensil, then it would cause the sharp edge to chip away.

Sharpening Of Ceramic Knives

You actually won’t need to care for this knife as much as regular metal ones. As with my old steel bladed knife, I had to sharpen it on a regular basis to sustain its cutting power. This amazing cutter, on the other hand, can retain its sharpness for a much longer time (about ten times longer). Besides, the ceramic blade is so hard that you cannot sharpen it with a normal knife sharpener. These regular consumer knife sharpeners are meant for steel-bladed knives only.

How do you keep Ceramic Knives sharp

Using a regular sharpener won't work because the only material hard enough to sharpen ceramic is diamond.

With ceramic blade, it takes a lot longer for its cutting edges to diminish. That is why you don’t need to sharpen it as frequently. I have been using mine constantly for about 3 months now and I have not seen any decline in its sharpness yet.

However, you will need to sharpen it at some point. When this time comes, it will require the use of a special sharpening service or a special sharpening tool.

Ceramic Vs Steel Knives

There are a lot of benefits to using ceramic knives instead of steel ones.

Ceramic vs steel blades

The main difference is the material the blade is made out of. The ceramic blade is lighter, sharper and the razor-sharp edge won't wear out.

The hardness rating of the ceramic knife is almost parallel to the hardness rating of diamonds. Because of this, the cutting edges of this knife will last so much longer without needing to be sharpened regularly. In fact, the edge won’t even need to be straightened either.

The secret is in the incredible zirconia ceramic that the blade is made out of so this ultra-sharp advanced ceramic blade will retain its initial sharpness years longer than steel blades.

When the time comes for your ceramic knife to be sharpened, it needs to be done by a special sharpener. As with your steel knives, depending on the usage, you'll probably need to sharpen them once a week.

The blades of ceramic knives will not retain any nasty food smells or stains after cutting food with them because they are not porous. These blades can be cleaned by merely rinsing it off in the sink.

Here Is An Overview Of The Differences Between The Knives:

  • Ceramic material is so much lighter than steel, making ceramic knives lighter weight in comparison to steel knives. As a result, you won’t need much effort to slice and chop your food. 
  • Since there are fewer pores in this material, there is a less chance of bacteria and germs being retained on the knife. This also makes it easier to clean the ceramic knife too.
  • The ceramic material can be described as “non-reactive.” This means it does not rust as metal does.

With all these advantages of ceramic knives, there are a few setbacks as I mention above. So let's go over these again. For instance, it is not a good idea to cut or slice harder food items with these knives. This would include bones, frozen meat, and anything else hard. If you attempt to cut hard things like this, the blade will likely chip. In addition, there is always the chance of you dropping the ceramic knife onto a hard surface or floor, resulting in the edge or tip getting damaged.

The functionality and the way in which you use the ceramic knife are huge factors of which knife sets you choose but It would be a good idea to have a set of steel knives also. You can still use this blade as your main tool and only use your steel knife when needed. 

Ceramic Blades Versus Shun Knives

Shun knives originate from Japan. They are world-renowned knives that are known for their fascinating sharpness and handmade design. Some of the most skilled knife makers in the world make these blades. Each blade must go through a minimum of 100 different steps by hand before it is finished, that is why they are very expensive.

Shun knives are higher quality stainless steel knives than what you find in the west. Most of us are accustomed to stainless steel blades that are heavy with a thick blade and have soft steel material. This design forces you to put more muscle and work into cutting your food. Plus, you will need to perform more maintenance on the blade because the steel material will dull out quicker.

As for the steel knives from Japan, they are thinner, lighter, and harder. This hard steel is an asset when you consider how the blade is sharp and thin. This means you can easily cut food without exhausting yourself at all. If you want to invest in one of these then it would make a good addition to your ceramic knife.

Titanium VS Ceramic Knives

Titanium might be good for a lot of things, but not for a carver material. Titanium is a softer and flimsier metal which is difficult to keep sharp. Ceramic is a much better alternative because it is very sharp in comparison.

The biggest advantages of titanium knives are that they’re corrosion-resistant and lightweight. Some people choose titanium knives for their kitchen because of this. If you don’t care about sharpness so much, then titanium blades might be a good choice for you.

    Oooo, I’m so glad that you decided to review this knife. I’m a total foodie, and I’ve been curious about these, but haven’t bought one yet, because I’ve heard that they chip. But I hadn’t thought about them being resistant to rust and smell, and now I’m definitely considering! I didn’t see any price comparisons here though – I’d love to see that info here!
