For more than 45 years, the Zwilling J.A. Henckels Four Star collection has set a high standard for dependable kitchen performance, and the Four Star Eco collection carries that legacy forward with a more sustainable approach. The Zwilling J.A. Henckels Four Star 5.5 in Flexible Boning Knife is built for cooks who demand precision, durability, and comfortable handling when preparing meat.
This boning knife features a long, thin, flexible 5.5-inch blade designed to follow the contours of meat as you work around bones and joints. Whether you’re trimming cuts of beef, poultry, pork, or other meats, the flexible blade gives you the control needed for clean, precise separation and detailed trimming. The fine V-edge is honed and hand-finished by skilled craftsmen to create a razor-sharp cutting edge that’s ready for serious kitchen work.
The blade is made from high-carbon stainless steel and precision-forged in Germany using the SIGMAFORGE process, creating a strong, single-piece forged construction. It’s also treated with FRIODUR ice-hardening technology, which increases hardness, helps the blade retain its edge, and provides resistance to staining and chipping. With a hardness rating of 55-58 HRC, the blade offers an excellent balance of sharpness, durability, and edge retention.
The matte black handle is crafted with a minimum of 75% recycled plastics, giving this classic collection a more environmentally conscious design without sacrificing everyday performance. Its ergonomic construction and concealed tang provide a comfortable, secure grip, making detailed trimming work easier to control.
Made in Solingen, Germany, this Four Star Eco boning knife combines traditional German craftsmanship with modern materials and manufacturing techniques. It’s dishwasher safe, although hand washing is recommended to help preserve its sharp edge and overall finish. Backed by a lifetime warranty, it’s a dependable addition to any kitchen where precision meat preparation matters.
From trimming meat to working carefully around joints and bones, the Zwilling J.A. Henckels Four Star 5.5 in Flexible Boning Knife delivers the control, sharpness, and German-made quality serious cooks can count on.
