TWIN 1731 is designed by the the world over acclaimed designer Matteo Thun. Years of labor culminated within the ZWILLING wedge geometry that improves comfort and optimizes cutting technique. This innovative curved bolster is meant to be an extension of the hand, supporting the pro grip with thumb and index finger at the blade Developed for bearings in aerospace engineering, the high performance Cronidur 30 steel boasts impressive toughness and corrosion resistance that may be 100 times higher than usual steel. Combined with ZWILLING’s signature ice-hardening technique, this FRIODUR blade is exceptionally sharp and durable. Every knife is precision-forged with ZWILLING’s SIGMAFORGE process, leading to a remarkably sturdy, balanced and flexible blade. With an incredibly sharp, laser-controlled edge, the knives are honed and hand-finished by probably the most skilled artisans.
