Technology and production

Special blend of the finest German steel, produced exclusively for Zwilling, with optimumThe optimum chromium-carbon ratio guarantees the best properties, with a hardness of approximately 57 HRC on the Rockwell scale. Combined with sophisticated manufacturing technologies, this results in knives that are robust, extremely durable, flexible, corrosion-resistant and long-lasting sharpness.
The knives are forged from a single piece of steel using patented SIGMAFORGE® technology, which further enhances the excellent properties of quality steel - the knives are stronger and the blades are more resistant to dulling. A special knife hardening process using the patented FRIODUR® technology, which consists in freeze hardening. Tempering the steel harmonises its molecular structure, removes internal stresses, creates exceptional flexibility and prevents blade breakage.
The tapered blade profile and laser-controlled "V" shaped blade ensure excellent and long-lasting sharpness. The flawless geometry and perfect balance of the blade ensure a precise and safe cutting guide that will not tire your hand even with prolonged use.
The guard (the reinforced steel part of the knife between the blade and the handle) not only serves to effectively protect the fingers, it provides protection for theIt also provides firm support for the fingers and balances the entire knife to make using the knife more comfortable and, above all, safer. Its robust design stabilises the transfer of force from the blade to the handle, preventing the knife from bending.
The ergonomically shaped handle is made of high-quality synthetic material that is durable impact and scratch resistant and remains stable even when exposed to temperature changes. The handle is firmly attached to the full tang by 3 sturdy rivets, the quality seamless connection of the handle to the blade ensures comfortable use and perfect hygiene (no food residues cling to the handle).

Maintenance of Zwilling knives

Washing and cleaning

Thanks to the special formula of the high-quality steel, Zwilling knives can be washed in the dishwasher, however, the knives should not beshould not be exposed to temperatures above 55°C and should not touch any other objects (pots, cutlery, other knives).Dishwasher detergents often contain aggressive chemicals that can damage the surface of the steel and the handles, and can shorten the life of the knives and the time they retain their high sharpness. Hand washing is gentler on knives and is therefore recommended. Wash knives with lukewarm water and a mild detergent with the soft side of a sponge.

Cutting mat

We recommend using a flexible cutting mat (cutting board) - wooden, silicone or plastic. Materials that are too hard such as glass, granite or ceramic can damage the blade and cutting edge under certain circumstances.

Sharpening / grinding

Sooner or later, even the best knife loses its original sharpness and needs to be sharpened. And because a dull knife is more dangerous than a sharp one, we recommend that you sharpen your knives regularly. If a knife develops a "tooth" or a deformation, we recommend that you have the knife in the hands of a specialist as soon as possible.
We recommend using genuine Zwilling sharpeners, whetstones and whetstones for sharpening.
We will be happy to arrange for knives to be sharpened directly at the manufacturer's premises or recommend a proven knife shop. The staff at Potten & Pannen - Staněk will be happy to demonstrate the correct knife sharpening procedure at any time.

Safe storage

Store your knives in a safe place (out of the reach of children), always making sure that the handle, not the blade, is facing you. The knives should not touch each other during storage.
Always store only cleaned and dried knives in the wooden knife block or on the magnetic rail.

The correct knife

Always use the right knife - the size and texture of the ingredients you are processing (meat, vegetables, fish, baked goods) varies greatly, so use specific cutting techniques and therefore a specific knife for each ingredient.
