Fox Knives FX-551 Saturn Folding Knife

Deploy swiftly using the patented, thumb-activated Radius lock system

The Fox Knives FX-551 Saturn Folding Knife is an evolution of classic Italian design. Designed by Denis Simonutti, this avant-garde folding dagger introduces striking visual symmetry alongside high-concept mechanical functionality. The premium N690Co stainless steel spear point blade features a coarse stonewashed finish that ensures long-term wear resistance. Built for fluid utility, it features the patented Radius lock mechanism, allowing you to deploy or retract the blade with a single intuitive rotation of the thumb button. The milled, gray anodized aluminum handle scales offer a secure, texture-rich grip, enhanced by a double guard profile that prevents your hand from slipping during work. Complete with an eye-catching red anodized pocket clip and a custom nylon storage pouch, this tool successfully bridges the gap between industrial design and daily carry efficiency.
