Steel is a metal and there are tonnes of types of steel. So performances may vary. As for ceramic, there are not as many types of them as steel but we all do know that ceramic is indeed very, very hard but that means it would be brittle too. But a hard edge means good edge retention and ceramic knives are so good at it until you do not even need to touch up the blade for a lifetime (near impossible to sharpen with a whetstone). However, a hard knife is a weak knife and will not be strong. So, there edge might snap or chip easily or the whole blade might shatter. Ceramic knives are for specific purposes and are not supposed to be treated like a steel knife with is stronger.

You never have to sharpen a ceramic knife but if you ever drop one which does happen once in a while say good by to it because it will shatter. By the way if your knife does fall let it fall and step away for safety reasons. I once got a bad cut reaching for a falling knife. Lesson learned !

A Ceramic knife is made of a ceramic zirconium oxide which is a powder that is compressed and fired in a kiln. It is so hard that it has to be sharpened with diamond dust because it is so hard. Steel knives are made from, well, steel. Zirconia has a hardness of 8.5 on a scale in which diamond is 10. Ordinary steel is around 4, but hardened steel is as high as 8. So even the very hardest steel is not as hard as a ceramic knife.
One of the very significant differences between them is that a ceramic knife is almost as brittle as glass. When you have something that is very hard, it is also very brittle. Steel that has been hardened is also brittle, but not as brittle as a ceramic.
Because it is so very hard a ceramic knife will hold an edge better than a steel knife and also have a sharper edge.
This extraordinary hardness means two things for a ceramic knife edge. It will last a lot longer and be very much harder to resharpen. In fact, for most practical purposes, it takes special equipment to resharpen a ceramic knife.
Since it is so hard to resharpen, care should be taken when using it. Don’t use a glass cutting board, since each time the knife touches it, there will be a microscopic chip flake off of the knife, gradually dulling it. Be careful not to drop it since impact with the floor is likely to cause it to shatter. These are unnecessary precautions with steel knives since they can be resharpened and (usually) won’t break when dropped.

There are quite a few differences between steel and ceramic knives, and choosing the kind that is best for you depends highly on how you cook, how involved you are in the kitchen, and what qualities you enjoy most in a knife.
Let’s take a look at some of the major differences. By and large, steel is far more durable than ceramic. By that, I mean that it is much more shatterproof. Ceramic knives are hard, but they suffer a brittleness that makes them break with too much pressure, where a steel knife would easily bend or give way. So, against harder objects, steel is the obvious choice.
Where ceramic comes out ahead is the quality and longevity of its edge. Ceramic knives from retailers like Fuller Brush are engineered with an extremely sharp edge, and unlike steel, ceramic doesn’t lose that edge quickly. It will still dull over time, but that might take a while. Steel, on the other hand, has to be regularly maintained in order to keep that sort of edge going.
