Knife Care Tips

Care instructions for a long knife life

What to cut on - the cutting surface

To prevent your knife blade from becoming dull, you should always cut on a wooden or plastic board. Boards made of metal, glass, marble or porcelain do not yield and the blade will become blunt more quickly. Soft wooden boards are recommended.

Cleaning Japanese kitchen knives properly

High-quality Japanese kitchen knives or hand-forged knives must not be put in the dishwasher! In the dishwasher your Japanese knife will be destroyed, because it oxidizes and the mostly used wooden handles swell up and possibly detach from the blade. You should clean your Japanese knife only by hand with a fine sponge, lukewarm water and if necessary a little detergent. After rinsing, the knife should be dried immediately. This also applies to highly rusty knives, as even here the formation of rust cannot be completely ruled out.

Storing your knives

You can store your Japanese knife e.g. in wooden knife blocks, in the supplied knife box or wrapped in a cloth. Be sure to remove any potential mechanical impact that could scratch the Japanese chef's knife. Magnetization of your knives by magnetic knife racks should be avoided, as magnetization of the knife steel can make sharpening your knives more difficult.

Japanese kitchen knife sharpening

Even the sharpest Japanese knife will not stay in its as-delivered condition forever and will need to be resharpened from time to time. Sharpening Japanese knives should only be done with the help of water stones. There are various whetstone options here, from coarse to very fine grits. The binder of the whetstones is also important, not just the grit itself. You can find more information on our homepage in the section Sharpening knives properly.

TIP #1 Hand wash only!
High-quality Japan knives or hand-forged knives must not be put in the dishwasher! In the dishwasher, your knife will be damaged because it oxidizes and the mostly used wooden handles swell up and may detach from the blade. You should only clean your knife by hand with a fine sponge, lukewarm water and a little detergent if needed.

TIP #2 Always dry Japanese chef's knives
After rinsing, the knife should be dried immediately to prevent rust from forming. This also applies to highly rust-resistant knives, because even here, rust formation cannot be completely ruled out.

TIP #7 Never use bones or frozen food!
Frozen and hard cuttings can damage the hard and thin blade of genuine Japanese knives. A Japanese knife is not to be confused with a Chinese cleaver

TIP #8 Proper cutting with Japanese knives
Use your knife for pulling and pushing movements and let the sharp knife work for you. Do not apply too much pressure and avoid levering motions, as this could damage the blade.

TIP #9 Oil as a protective coating
Protect your blade surface with the help of food-safe oils and greases. Regular application of olive oil, for example, will protect the blade from corrosion. Depending on the Japanese knife steel, a patina will form on the blade, this is useful and desired.

TIP #10 Use the back of the blade
To move food after cutting, use the back of the blade instead of the cutting edge. This will protect the blade and keep your knife sharp longer.
