Zwilling Four Star 7-inch Flexible Fillet Knife (1001582)

The Zwilling Four Star 7-inch Flexible Fillet Knife is expertly crafted to provide the precision and control needed for delicate butchery tasks. Its long, slender blade is specifically designed for filleting whole fish, allowing you to move cleanly along the backbone and under the skin with ease. The blade's significant flexibility enables it to follow the contours of fish and other proteins precisely, ensuring you achieve perfect, uniform fillets while minimizing waste. This knife is also highly effective for trimming silver skin or wafer-thin slices from larger cuts of meat.


At the core of its performance is Zwilling's proprietary special formula high-carbon stainless steel. The blade is precision-forged from a single piece of this steel using the SIGMAFORGE process, which guarantees perfect geometry, exceptional stability, and a precise cutting edge. The blade then undergoes Zwilling's signature FRIODUR ice-hardening process. This thermal treatment enhances the steel's structure, resulting in a blade with remarkable durability, superior corrosion resistance, and a sharpness that lasts.


Comfort and safety are hallmarks of the Four Star series. The seamless polypropylene handle is ergonomically designed for a comfortable, fatigue-free grip, even during extended use. This seamless transition from handle to bolster enhances the knife's balance and improves hygiene by eliminating spaces where food particles could collect. The full bolster provides added weight for balance and acts as a finger guard, protecting your hand during intricate cuts. Proudly made in Germany, this knife represents a legacy of quality craftsmanship and cutlery innovation.
