Best Knives for the Kitchen [Are Ceramic Knives Any Good?]

Looking for knives that don’t need sharpening all that often? Ceramic knives are considered one of the sharpest and they stay sharp longer than traditional knives. But, are ceramic knives good to use in the kitchen? Here I cover the ceramic knife advantage, plus downsides, and what to consider if you’re looking for one among the many ceramic knife sets on the market right now.

To avoid confusion: This article discusses ceramic knives, meaning knives with ceramic blades, NOT the ceramic-coated type.

Are ceramic knives good in the kitchen?

Many folk consider ceramic knives good to have in the kitchen because…

1. They are lightweight to handle
2. Don’t rust
3. They are easy to clean. A quick rinse and wipe with a kitchen towel.
4. Unlike metal, they won’t oxidize. They are non-corrosive.
5. They perform better for longer — the cutting edge stays sharper longer
6. They endure acids and are nonporous
7. They resist bacteria and germs
8. They are made of eco-friendly material

What you need to know…

• Ceramic knives (while strong and all of the above) are fragile. I wrote about this in my article on what not to do with them, which is worth a read if you are considering buying a set.

How are ceramic knives made?

Here’s how ceramic knives are made…

• High-grade zirconium dioxide (zirconium #4 is the highest grade) is used in the blades of ceramic knives.
• Ceramic knife makers treat zircon sand to produce zirconium dioxide (zirconia).
• The zirconia goes through a lengthy firing process. The end result are ceramic knife blades that are rust- and corrosion-proof and inert (meaning no impact on food flavor).

Compare this to the ceramic coating of nonstick cookware, which is derived from silica sand.

Video on how ceramic knives are made

This 8-min “How Do They Do It” video shows what it takes to make the Kyocera ceramic knife sets.

Enough metal is added to the mix so that ceramic knives are not a security risk, i.e. they can be detected by airport scanners and the like.

About that ceramic blade color

You will notice the ceramic blades will be either white or black. Here’s why ceramic knives differ in color. Going on what the manufacturers say, a black blade has had extra treatment for strength. You can expect to pay more for black blades than white blades.

A black blade indicates the knife has gone through isostatic pressing to increase the density and strength of the ceramics. The additional cold or hot isostatic pressing in the process creates a tougher blade as it produces a tighter knit between the ceramic molecules.

Whereas a hot-isostatic press (HIP) involves extra firing at high pressures, a cold-isostatic pressing (CIP) is performed at room temperatures but with higher pressure than for HIP. You can learn more about hot- and cold-isostatic pressing here.

Ceramic knife advantage

The two main advantages of a ceramic knife are 1) a cutting edge that stays sharp and 2) the ease of precision cutting. These performance advantages are mentioned again and again in ceramic knives reviews.

This means paper-thin tomato slices and perfectly diced onions for you in the kitchen. Be sure to watch the video above (at about 8:12) to see how a ceramic knife finely slices a fillet of fish into wafer-thin slices.

Apart from being better than steel knives for fine slicing jobs at home, ceramic knives stay sharper for longer. This is great, if you prefer not to have the inconvenience of having to sharpen knives too often.

As well, using a ceramic knife means you have a lightweight knife that will never rust and is easy to clean. And, it is made of eco-friendly material.

Ceramic knife care

On how to care for ceramic knives…

• I recommend you hand wash only. Ceramic knives are super easy to clean, so this is not a hassle.
• Always store in their protective covers and a knife block is also recommended.
• As said above, avoid heavy duty cutting or prying, e.g., use steel knives with frozen food, bones, or hard cheese (Parmesan, cheddar etc.), not your best ceramic knives!
• The best and safest way to store ceramic knives is with a bamboo knife block (see below).

How best to protect knife blades?

Knife sheaths help to protect the knife blades while storing them – I wrote about the best ways to store sharp knives. There are also the knife blocks and drawer knife holders are convenient and great savers of ceramic blades. Both of these are available in modern bamboo designs.

How to sharpen ceramic knives

How do you sharpen a ceramic knife? Manufacturers recommend sending ceramic knives to professionals for sharpening. Some brands like Kyocera offer free lifetime sharpening (though you may need to pay for transport costs). If you want to sharpen them yourself, you need to use a diamond coated knife sharpener.

There are electric ceramic knife sharpeners with 2-stage diamond sharpening wheels, designed for ceramic kitchen knives. You can opt for a manual approach with a set of stones but a sharpening rod or triangle that you use for steel knives is not always recommended.

You’ll find more on options for sharpening ceramic knives in my article on how to sharpen ceramic knives.

Pros and cons of ceramic knives

Ceramic knives are ultra sharp and perfect for precision slicing of tomatoes or similar produce or fine slicing of boneless meats. You can’t go wrong in adding at least one ceramic knife to your kitchen knife set for that reason.

• Super sharp
• Retain sharpness longer than steel
• Won’t corrode in harsh environments
• Do not conduct electricity at room temperature
• Resistant to strong acid and caustic substances
• Lighter than steel

But there are some cons…

• Lack of versatility. Not for heavy-duty chopping and prying, e.g. with bones or frozen foods, as this can lead to chipping of the blades.
• Fragile. Though they are harder and hold their edge longer, they are more brittle than steel knives. Take care not to drop the knives onto hard surfaces. The latest design processes, however, have reduced the risk of breakage.
• Need special sharpening stone.

FAQs

Final thoughts

A good set of knives will save you time and show your finesse. You won’t go wrong with at least one or two ceramic knives complementing your high-carbon stainless steel set.

The Kyocera brand is my favorite of these – scroll back to the table to take a quick look at all the reviewed items and see how it compares.
