What Are Ceramic Knives?
Ceramic is a material that’s shaped, then hardened into its final form with exposure to high temperatures. You might be familiar with ceramic in the form of plates and coffee mugs. However, a ceramic knife uses a different kind of ceramic.
These knives are usually made with zirconia: you might recognize this material from cubic zirconia, or synthetic diamonds. Zirconia is incredibly hard — harder than steel, if not quite as hard as real diamonds. That’s why it works so well in knives.
You won’t find a full set of ceramic knives like you would with steel knives. These aren’t all-purpose tools like regular knives are, but they work well for specialty uses.
It’s important to know that ceramic knives still break easily, even though they’re hard. If you try to use your ceramic knife to cut something that’s too hard, it will probably break. You can’t apply pressure to the flat of the blade to do things like crush garlic without snapping the blade, either.
These ultra-thin knives also chip easily. Although you can even out chips when you learn how to sharpen ceramic knives, it’s best to replace a seriously chipped blade instead. Ceramic knives also aren’t cheap. They’re considered a high-end item, so they cost at least as much as a high-end steel knife, if not more.
Reasons To Buy Ceramic Knives
Although there are some drawbacks to using them, there are also lots of reasons to buy and learn how to sharpen ceramic knives. These are our favorite reasons to make the purchase.
Easily Slice Soft Foods
You can’t use a ceramic knife to cut through tough things like frozen foods. But if you want to slice anything from cold butter to fruits to herbs, a ceramic knife is your best bet. You’ll still need your other knives for general purpose uses.
But you can use your ceramic knives when you need clean cuts, such as for making the perfect twist of lemon to garnish your drink. These knives also work well for making super-thin slices, since they’re so sharp. Learning how to sharpen ceramic knives will help you get those delicate, perfect cuts every time.
Stays Sharp Longer
Once you learn how to sharpen ceramic knives, you won’t need to put that knowledge to the test very often. These knives are known for maintaining a sharp edge for far longer than metal knives can. This reduces your time spent making your knives sharp and safe to use.
Although a ceramic knife costs more than a regular knife, it’s an investment that will last a long time, so it’s easy to justify the cost.
Clean and Odor-Free
Ceramic isn’t porous, so there’s nowhere for dirt, residue, or odors to collect. Although it might seem surprising, metal knives actually are harder to clean. With a ceramic knife, you can just rinse it under warm water and have it come out almost completely clean. The material doesn’t stain, so it looks good even after lots of use.
Ceramic knives also make it easy to prep multiple foods at once without transferring odors. If you cut something pungent, you can just rinse your knife off before cutting the next thing — the smell won’t transfer.
Since ceramic knives aren’t made of metal, they’ll never rust. This also helps extend their lifespan even further.
Ceramic knives are far lighter than steel ones. This makes them very easy to control, although you will notice that you’ll need to push more to make a cut since the weight of the knife can’t do it for you.
Caring For Ceramic Knives
In addition to knowing how to sharpen ceramic knives, there are some basic things you should do to care for these tools. Let’s take a look at how to keep your ceramic knife working like new for longer.
Avoid the Dishwasher
You might have read that ceramic is dishwasher-safe. However, washing any knife in the dishwasher — especially a ceramic one — is a bad idea. The pressure of the water and the possible jostling inside the dishwasher can easily damage your knives, especially the ceramic ones.
They might come out of the dishwasher chipped or broken, so it’s best to wash them by hand. Plus, ceramic’s so easy to keep clean that handwashing is easy.
Take Extra Care
Dropping your ceramic knives almost guarantees that they’ll chip or break. These knives should be handled delicately, never bumped or dropped. That said, you should also take care not to drop your steel knives.
The blade could bend, and you’ll need a professional to fix it. Also, even though you’ll learn how to sharpen ceramic knives, you should never cut with them on the wrong surface. Avoid cutting on countertops made of materials like marble or granite. Instead, use a soft cutting board every time.
Store Them Properly
You’ll want to store your ceramic knives with a protective cover so they can’t get damaged. You can’t place them on your magnetic strip since they’re not metal, but make sure they go somewhere where they won’t get bumped and broken.
Know What to Cut
Even fruits and vegetables can have hard seeds and pits inside that will damage your ceramic knife. Only cut things that have nothing hard inside to chip or break the blade.
The Problem With How To Sharpen Ceramic Knives
Ceramic knives last a long time with proper maintenance and don’t need to be sharpened very often. However, learning how to sharpen ceramic knives properly is critical, because they can’t be sharpened as easily as steel knives.
The material is nearly as hard as diamonds so that regular sharpening tools won’t do any good. Since ceramic is so brittle, it’s also hard to sharpen without breaking your nice kitchen tool.
If you put too much pressure on the blade while sharpening it, it will break — and it doesn’t take much to put too much pressure on a ceramic knife. People who have sharpened lots of metal knives often have difficulty learning how to sharpen ceramic knives.
Your muscle memory from sharpening steel won’t serve you well: you’re probably used to using pressure and feeling the knife spring back, which is exactly what will break a ceramic knife. However, anyone can learn how to sharpen ceramic knives with the right techniques that will keep them functioning well for years. Let’s get into how it works.
How To Sharpen Ceramic Knives
Knowing how to sharpen ceramic knives will save you money because you won’t need to pay for professional sharpening. Keeping your knife sharp also reduces the chances that you’ll need to replace it. Start with these tools and techniques.
The Tools You’ll Need
One of the only things harder than the ceramic of your knife is a diamond. This means you’ll need diamond tools to sharpen your knife. With that in mind, you have a few different options when it comes to tools. Here are the main ones to choose between.
1. Sharpening Rod
A sharpening rod made of diamond steel can get your blade sharp again. If you use this tool, you should also get a pair of protective gloves for your hands. Make sure to wipe down the rod after you use it to get rid of any bits of ceramic left behind.
2. Electric Sharpener
Electric sharpeners do some of the work for you, making learning how to sharpen ceramic knives a little easier. Again, you’ll want one that uses diamond, otherwise it won’t work to sharpen your ceramic knife.
This greatly narrows down the pool of options, since most electric knife sharpeners don’t use diamond. Even if you use an electric sharpener, you should still wear cut-resistant gloves to protect your hands.
Other Tips For How To Sharpen Ceramic Knives
Once you get the hand of using these basic tools, you’ll find that it’s fairly easy to learn how to sharpen ceramic knives on your own. However, these tips will help you get the best results every time.
i. Use the Right Slot
Many electric knife sharpeners have different slots for different levels of sharpening. Since ceramic blades don’t get dull easily, you probably won’t need the most intense level. Instead, use the fine slot for light sharpening. That way, you won’t take off too much of the delicate blade.
ii. Store Them Properly
In addition to keeping your knives from breaking, proper storage also prevents your ceramic knives from getting dull. Make sure to always put the protective cover on when your knife’s not in use.
Don’t keep your ceramic knife in a drawer, where other things can bump into it and damage it. Give it its own designated place in the kitchen instead, like a knife tray or a high-quality knife block.
iii. Don’t Buy a Ceramic Knife Sharpener
If you see a product labeled “ceramic knife sharpener,” you might think it’s designed for ceramic knives. However, these tools actually use ceramic to sharpen regular knives. Since your blade is already ceramic, these tools won’t make the knife any sharper. Look for tools labeled “diamond knife sharpener” instead.
Are Ceramic Knives Right For You?
Now that you know how to sharpen ceramic knives, you can probably tell whether or not one deserves a place in your kitchen. You can definitely have a well-stocked kitchen and cook excellent meals without ever buying a ceramic knife.
They aren’t essential, but they are a nice luxury for passionate cooks. If you find yourself needing to make delicate cuts in things like fruits, vegetables, poultry, or fish, a ceramic knife will make your life easier.
Knowing how to sharpen ceramic knives will let you keep that investment working well for years to come. Will you splurge for one of these specialty knives or not? Leave a comment and let us know!
