The FOUR STAR® series of the German company ZWILLING J. A. Henckels is already a legend among quality knives, often sought after by master chefs. It was first introduced to the market in 1976 and thanks to the use of high quality materials and the revolutionary technology of knife production with a seamless synthetic handle, it became one of the best selling knives in the world. These are very sharp, high quality knives made of special steel by a patented method of forging from a single piece of steel, which boasts a high degree of comfort and safety in their use.

Sharp knives, which also retain their sharpness for a long time, are indispensable in the kitchen not only for hobby cooks. In the FOUR STAR® series you will find knives of different sizes and blade shapes. The ZWILLING brand is a sign of quality, we highly recommend it!

Technologies and materials used

For the production of the knives, a special high-quality steel with an optimum amount of chromium and carbon was used, produced according to special requirements exclusively for ZWILLING J. A. Henckels. With a Rockwell hardness of approx. 57 HRC, this steel is flexible, has good initial cutting performance, long blade life and perfect corrosion resistance. Knives made of this special steel are also easy to sharpen. Confirmation of the correct "recipe" for its production is the fact that over 100 million knives have already been made from it without changing the steel composition.

The properties of the steel are further enhanced for the purpose of knife production by a special patented FRIODUR® hardening method, whereby the steel is frozen to -70 °C after heating to a temperature of over 1000 °C and hardening to -70 °C and then heated twice more to a temperature of approx. 250 °C. The resulting molecular structure significantly increases the hardness, toughness and corrosion resistance of the knife.

The blade of the knife is forged from a single piece of steel using the SIGMAFORGE®method, which improves the properties of the steel. Blades forged in this way have a denser and more homogeneous structure, which ensures greater strength, toughness and resistance to dulling.

The stable blade and the perfect geometry of the blade result in exceptional cutting performance and precise control in the cut. The sharp angle provides even more sharpness, which makes slicing more enjoyable. Thanks to the wedge-shaped cut, the knife penetrates food effortlessly.

The Standard crossguard is integrated as part of the blade in one piece of steel. Ensures correct weight distribution, protects fingers from slipping on the blade and ensures precise control of the knife.

The ergonomic, splash-free handle is made of durable synthetic material that is shatterproof, impact-resistant and resistant to food acids. It is dishwasher safe. The perfect bonding of the individual parts prevents the trapping of deposits and bacteria, so the knives meet strict hygiene standards.

Maintenance of ZWILLING knives

Knives with plastic handles can be washed in the dishwasher, but it is recommended to wash them by hand, which is gentler on the knife. If you prefer to wash in the dishwasher, please bear in mind that high-quality knives can be damaged if they come into contact with other cutlery, pots or pans during the washing process. When putting dishes in the dishwasher, it is therefore essential to check that the blades of the blades cannot touch other objects. The manufacturer also recommends an economy programme with a maximum temperature of 55 °C for possible use of the dishwasher.

Every knife needs to be sharpened from time to time.
