Knives have been around almost as long as we’ve had tools. And while not a lot has changed over time, there have been a few advancements. The latest comes in the form of a new material—ceramic blades. Unlike your ceramic flowerpots, the ceramic used for knives is super-hard and can be honed to a smooth, sharp edge. That’s not to say that ceramic knives are better than metal knives, but there are pros and cons to both materials

Ceramic knives are harder than steel knives, rating close to diamonds...MORE on the hardness scale. Because of that harness, they hold an edge longer so they don’t need to be sharpened as often, and they don’t need to be honed to straighten their edge. However, that hardness also means that ceramic can’t be sharpened with most of the traditional knife-sharpening materials that were designed for steel knives. The oilstones that have been in the family for years aren’t hard enough to cope with ceramic knives, and electric sharpeners can chip or break ceramic blades.

Some ceramic knives can be returned to the manufacturer for professional sharpening, but that’s inconvenient. Fortunately, as ceramic knives become more popular, there are new sharpening stones being made that have embedded diamond dust. There are also some electric sharpeners that can now handle sharpening ceramic knives.

Ceramic knives are also stain-resistant and rust-proof. They aren’t affected by acids in foods and won’t cause browning. They’re easy to clean, they don’t absorb odors, and they're lightweight.

While any sharp knife is good for slicing foods thinly, ceramic knives are particularly well suited for that task, whether you’re slicing paper-thin radishes or peeling a tomato. They’re also good for slashing bread dough before baking.

Just like steel knives, where the precise type of metal can vary, there are different types of ceramic materials being used for ceramic knives today, with many manufacturers using proprietary materials. Many ceramic knives have a bright white blade, but some are being made with black blades, as well.

The biggest downside to ceramic knives is that along with the super-hardness comes brittleness. They can’t be used for boning, prying, or cutting frozen foods or for any tasks where the knife is likely to bend. They shouldn’t be used for chopping if the blade will hit the cutting board sharply. And they shouldn’t be dropped. If a steel knife hits the floor you might bend the tip or embed it in the floor, but if you drop a ceramic knife, it’s likely to break or shatter.

Steel blades have their downsides, too. Depending on the type of steel used, they can be prone to staining or even rusting. They need to be sharpened more often than ceramic blades. And they are heavier than ceramic knives.

Just like any other knife choice, the final decision between ceramic or steel comes down to personal preference. A person who often drops their knives won’t have a good relationship with a ceramic knife, while someone who hates having to sharpen knives will appreciate how long the edge lasts on a ceramic knife. Here, the best ceramic knives for you.
