How safe are the ceramic knife: Ceramic Knives Pros and Cons

Ceramic knives are a relatively new addition to kitchens everywhere. These knives are durable and sharp, and many people find them to be safer than traditional knives. However, not all ceramic knives are alike.

In this blog post, we’ll take a look at how safe are the ceramic knife and ceramic knives pros and cons. We will give you some tips on how to use and care for your ceramic knife.

Ceramic blades are mostly made of zirconium dioxide. Zirconium dioxide is extremely resistant to acids when it has been thermally pretreated. Ceramics made from this material are harder and wear out much more slowly than hardened steel.

Are ceramic knives safe?

When it comes to safety, ceramic knives are considered safe to use, as long as they are used properly and with caution.

The blade is made of zirconium dioxide, which is extremely hard and very sharp.

This makes the knives more brittle than metal knives, which means they can chip or break if mishandled.

Ceramic knives should only be used for slicing vegetables, boneless meats, and fruits.

They should not be used for chopping, as this could cause the blade to chip or break. Also, never use ceramic knives to cut raw meats, as the blade may chip and the bacteria from the raw meat could contaminate the ceramic knife and cause food poisoning.

Ceramic knives are considered safe for use in food preparation. They are made from non-toxic, inorganic materials and do not contain any harmful chemicals that could leach into food.
It’s worth mentioning that ceramic knives may contain small amount of lead or cadmium if the ceramic material is not food-grade.

So it’s important to ensure that the ceramic knife you purchase is made from food-grade materials and that it is free of lead and cadmium.

Advantages of ceramic knives

Ceramic knives not only stand out for their attractive design and appearance, but also for being able to unseat traditional steel knives thanks to their versatility. In addition, they have a number of features with which they offer great performance:

• The knife blade is made of zirconium oxide powder. This makes it a highly wear-resistant kitchen utensil and the cutting edge remains perfect for much longer than other knives. By this we mean that the ceramic does not contain metal ions, so it will never rust.
• How are ceramic knives sharpened? Ceramic knives are sharpened with diamond discs to achieve an extremely sharp blade, which allows you to make fine cuts in a simple and precise way. In turn, once sharpened, a ceramic blade can last for years before needing to be re-sharpened.
• If you try one of these knives with a ceramic blade, you will notice that it stands out for its lightness, since this material is lighter and weighs less than a steel blade.
• The handles of ceramic knives offer great ergonomics, so they can be handled comfortably, thus minimizing the risk of cuts.
• The ceramic blade of the knives is a non-porous material, so it does not accumulate dirt and does not retain the odor or taste of food.

Disadvantages of ceramic knives

Ceramic knives are fragile because they are made of a material that is not as flexible as steel. For this reason, it is advisable to be careful with those foods that are cut. So what can you cut with a ceramic knife? It can be used to make thin cuts of boneless meat, soft cheeses, etc. Some other disadvantages are:

• Ceramic knives are not recommended for cutting meat bones or fish bones because the blade could break.
• Ceramic knives are not suitable to use on all surfaces. We advise you to always cut on a wooden or plastic cutting board because if you cut on a hard surface such as a granite or marble countertop, the ceramic blade of the knife could break.
• Do not be overconfident when cutting with this ceramic utensil, as its lighter, sharper blade can cause you to cut deeply if you are overconfident.
• Ceramic knives should not be put in the dishwasher because the pressurized water could cause them to collide with other utensils and scratch them. We also recommend storing them in a knife block.
• The ceramic blade of the knives must be sharpened with diamond machines, which is not common in homes, so you will probably have to resort to a domestic ceramic knife sharpener, which will not guarantee such a good sharpening.
• If a ceramic knife loses its edge, it is difficult to get it back to its original sharpness.

• The most important thing when grinding is to keep the correct angle constant. This is between 10 and 15 degrees for the tip of the blade. Now place the other hand near the cutting edge to additionally fix the blade and guide the knife in both directions at the specified angle over the sharpening stone.
• Once you can feel a small burr at the tip of the knife’s cutting edge, you can continue sharpening the center of the blade. To do this, pull the knife diagonally across the sharpening stone at a 60° angle. As soon as you can feel a ridge here as well, you can turn your attention to the last part of the blade.
• Depending on the size of the whetstone and knife, these steps may need to be repeated a number of times. If dust or debris settles on the grinder, you can blow it off after use or wipe it off with water. If you use water, you must always wipe the grinder dry, otherwise rust can quickly develop.
• Repeat the process for the spine of the blade.
