A good kitchen knife can accompany its owner for many years. It still needs proper care. A blade left damp, repeated dishwasher cycles, or cutting on a surface that is too hard can quickly reduce its performance.
Maintenance actually comes down to a few simple habits: clean the knife after use, dry it immediately, preserve its edge, sharpen it when needed, and store it without exposing the blade to impacts.
These tips are especially important for Japanese knives, whose fine edge deserves a little more attention than a standard utensil.
How do you clean a knife without damaging it?
The best method is also the simplest: wash it by hand in lukewarm water, using a soft sponge and a little dish soap.
Clean the blade soon after use, especially after working with acidic foods such as citrus fruits, tomatoes, or certain fruits. Rinse it, then dry it immediately with a clean cloth.
Avoid leaving the knife to soak in the sink. In addition to the risk of cutting yourself when you put your hand into the water, prolonged moisture is not good for either the steel or certain materials used in the handle.
On the Sakoma chef knife, for example, Maison Damas recommends hand washing followed by immediate drying to preserve the blade and its wooden handle.
Can a kitchen knife go in the dishwasher?
For a quality knife, it is better to avoid it.
The problem is not only the water. A dishwasher cycle combines heat, prolonged moisture, fairly harsh detergents, and possible contact with other cutlery.
These conditions can accelerate edge wear, mark the blade surface, and gradually damage certain handles.
Hand washing takes less than a minute and remains by far preferable for preserving a Japanese or professional knife.
Why should the blade be dried immediately?
Even when a steel offers good corrosion resistance, it is not wise to let water dry naturally on its surface.
Immediate drying reduces marks, moisture around the handle, and the risk of oxidation on the most sensitive steels.
This precaution becomes even more important with carbon steel, which may react more strongly to moisture and acidic foods. In that case, a very thin layer of food-safe mineral oil or oil intended for blade care can be used before a long storage period.
On the other hand, avoid applying just any cooking oil: some can go rancid over time.
How do you care for a wooden handle?
Wood does not appreciate prolonged soaking or repeated temperature changes.
When cleaning, simply wipe the handle with the sponge and then dry it carefully. If it is natural wood with a finish that allows it and it begins to look very dry, a small amount of food-safe oil can help nourish the material.
Before any treatment, however, check the recommendations specific to the model: not all handles are finished in the same way.
How often should a knife be sharpened?
There is no universal schedule. The frequency depends mainly on use, the steel, the blade hardness, the cutting board used, and the way the knife is handled.
A professional cook using a blade for several hours a day will naturally need to sharpen it more often than someone cooking three times a week.
The best indicator remains the knife’s behavior. When you have to start pushing harder to cut through a tomato, or when a cut that was once clean becomes less precise, the edge probably needs attention.
Sharpening stone, honing steel, or sharpener: what’s the difference?
| Tool | Main role | When to use it? |
|---|---|---|
| Sharpening stone | Reform and then refine the edge | When the knife cuts much less effectively |
| Honing steel | Regular edge maintenance depending on the material | Between sharpenings |
| Sharpener | Guided or mechanical solution | Depending on the blade type and the device |
The classic honing steel is mainly used to maintain edge alignment. Ceramic or diamond-coated versions can remove more material.
A manual or electric sharpener can be convenient, but its angle must be compatible with the blade. A device that is too aggressive can remove far too much steel unnecessarily.
For finer control, a stone remains an excellent solution.
How do you sharpen a knife with a stone?
A sharpening stone generally has different grit levels. The lower the number, the faster the stone removes material; higher grits are more suited to refining and polishing the edge.
The pierre à aiguiser Maison Damas, for example, has two sides: a 1000 grit for resharpening and a 6000 grit for a finer finish.
The general principle is to:
- prepare the stone according to its instructions;
- place it on a stable surface;
- maintain a consistent angle;
- work along the full length of the edge;
- treat both sides consistently;
- finish with a finer grit if needed.
The regularity of the sharpening angle matters more than speed. For a beginner, a few slow, controlled strokes are better than fast, irregular sharpening.
What is the difference between sharpening and honing?
In everyday language, the two terms are often used as synonyms.
In practice, sharpening generally refers to restoring an effective cutting geometry to the knife by removing a small amount of material. Honing with a steel can, in turn, correct or maintain the edge between more substantial sharpening sessions.
The goal is not to sharpen constantly. Removing metal when the blade still cuts perfectly offers no benefit.
Which cutting board should you use to preserve the edge?
The choice of cutting surface has a major impact on edge longevity.
Wood and certain food-safe plastics provide a relatively forgiving surface. By contrast, cutting directly on glass, marble, granite, a plate, or a very hard countertop quickly dulls a blade.
A perfectly maintained knife used every day on a mineral surface will therefore quickly lose part of its edge.
How should you store your knives properly?
As much as possible, avoid throwing several knives loosely into a drawer. The blades can knock against each other, scratch, or damage their edge. This also increases the risk of cutting yourself while reaching for a utensil.
Several solutions are available:
- a suitable knife block;
- a magnetic strip;
- an individual sheath;
- a blade guard;
- a case for professional transport.
The blade guard Maison Damas, for example, limits contact and impact during storage or transport.
To keep several knives accessible without stacking them, the Maison Damas wall mount uses a magnetic system that keeps the blades separated.
Do Japanese knives require special care?
Modern Japanese knives can use different types of steel, but they often share a relatively fine, precise edge.
You should therefore avoid twisting motions, bones, frozen foods, and very hard surfaces. A kitchen knife is designed for cutting: it should not be used as a screwdriver, a lever, or a tool to open rigid packaging.
To discover another type of blade beyond those presented in our latest guides, the Nakiri Niigata is a good example of a Japanese blade dedicated to precise vegetable prep.
And what about a pocket knife or a Laguiole?
Care for a folding knife adds one important point: the mechanism.
After cleaning, the pivot and moving parts must remain clean and dry. Depending on the model, a very small amount of compatible lubricant may be used on the joint.
A Laguiole-style knife or another pocket knife may also feature wood, horn, or other natural materials. You should therefore follow the manufacturer’s recommendations before using any care product.
For a fixed kitchen knife, the focus is more on the blade, handle, and edge; for a folding knife, the mechanism is simply an added element.
The mistakes that damage a knife the fastest
- Leaving it to soak in water.
- Putting it regularly in the dishwasher.
- Storing it loosely with other utensils.
- Cutting on glass, marble, or a plate.
- Using the blade to pry.
- Cutting bones or frozen food with a blade not designed for it.
- Sharpening too often or at the wrong angle.
- Leaving moisture on the steel before storing it.
How can you really extend a knife’s lifespan?
Good care only takes a few minutes in the end.
Wash your knife by hand, dry it immediately, use a suitable cutting board, and store the blade in a way that avoids impact. When the edge truly begins to lose its performance, maintain it with the proper tool rather than waiting until it is completely dull.
These simple habits help preserve the pleasure of precise cutting for longer and reduce the need for major edge maintenance.

FAQ: knife care, cleaning, and sharpening
How do you clean a knife without damaging it?
Wash it by hand with warm water, a soft sponge, and a little dish soap. Rinse it, then dry the blade and handle immediately with a clean cloth. Avoid leaving it to soak.
Can you put a kitchen knife in the dishwasher?
It is best to avoid doing so. Heat, prolonged moisture, detergents, and contact with other utensils can gradually damage the edge, the steel, and certain materials used for the handle.
How often should a knife be sharpened?
There is no fixed schedule. Sharpen it when the blade genuinely begins to lose its effectiveness. The frequency depends on use, the steel, the cutting board used, and cutting habits.
Which sharpening stone should you use for a knife?
A grit around 1000 works well to restore an effective edge to a dull blade. A finer grit, such as 6000, then allows you to refine and polish the edge further.
What is the difference between a stone, a honing steel, and a sharpener?
The stone allows you to work precisely on the geometry of the edge. The honing steel is mainly used to maintain the edge between sharpenings, depending on its material. A sharpener offers a more guided solution, but it must be compatible with the angle and type of blade.
How can you prevent rust on a blade?
Do not leave the knife wet after use. Wash it, dry it immediately, and store it in a dry place. For certain carbon steels, a very thin layer of food-safe oil can be useful during long-term storage.
What is the best way to store a knife?
A magnetic strip, a suitable block, or a blade guard help prevent impacts between blades. Avoid storing a quality knife loosely in a drawer with other utensils.
Is the care of a pocket knife different?
Yes, because you also need to maintain the mechanism and pivot of the knife. They must stay clean and dry. For a fixed kitchen blade, care mainly concerns the edge, the steel, the handle, and storage.
