The FOUR STAR series by ZWILLING J.A. Henckels stands as their top-selling knife collection globally. Crafted by skilled artisans, these knives exemplify safety, ergonomics, and comfort. Their seamless transition from bolster to handle ensures extended comfort during prolonged use, with the bolster also acting as a secure finger guard. Made from a proprietary special formula steel refined over 280 years, these knives incorporate ZWILLING's renowned ice-hardening technique, resulting in FRIODUR blades that are exceptionally hard, sharp, stain-resistant, and durable.

Each knife in the FOUR STAR series is precision-forged from a single piece of steel using SIGMAFORGE technology, which ensures robustness, balance, and flexibility in the blade. The 10-inch blade, notable for its curved cutting edge and blunt back, simplifies chopping, dicing, and mincing with a rocking motion on the cutting edge, enhancing both efficiency and safety in the kitchen.

Introduced in 1976, the FOUR STAR series was developed in collaboration with professional chefs, leading to the creation of fully forged knives with molded handles. These knives cater to a variety of culinary tasks, including paring, bread slicing, peeling, utility, carving, and chef's knives, among others. Available in open stock, block sets, and gift sets, FOUR STAR knives maintain a high standard of construction, incorporating high-carbon, no-stain steel forged under the Sigmaforge standard for superior quality, lasting sharpness, and precise geometry.

The knives undergo Henckels' Friodur ice-hardening process, enhancing corrosion resistance and cutting-edge retention. The ergonomic handles, made from high-impact polypropylene, are seamlessly bonded to the blades for durability and sanitation, featuring a super bolster for added weight, safety, and balance. These features ensure comfort and precision during use, backed by the knives' full tang construction for optimal balance and strength.

Key attributes include a Rockwell Hardness rating of 57, indicating excellent edge retention, and a 15-degree edge angle per side, ensuring sharpness and durability. The knives are dishwasher-safe for easy maintenance, although hand-washing is recommended to preserve their longevity. J.A. Henckels guarantees the quality of their knives with a full warranty, reflecting their commitment to craftsmanship and customer satisfaction.

Established in 1731, J.A. Henckels is one of the world's oldest and most esteemed cutlery manufacturers, renowned for producing knives that embody durability and precision. The FOUR STAR series continues to uphold this legacy, offering professional-grade tools that meet the rigorous demands of both home cooks and culinary professionals alike.
