Product Description
The Fidus™ is a masterclass in functional reliability, designed by the legendary Michael Walker—the inventor of the modern liner lock. Its name is derived from the Latin word for "trustworthy" or "loyal," a fitting title for a tool engineered to be a constant, dependable companion for everyday carry. Combining Walker's iconic mechanical DNA with a streamlined, modern silhouette, the Fidus prioritizes ergonomic comfort and surgical cutting precision, making it an ideal choice for the user who values a knife that performs with quiet, consistent excellence.
The 3.22" drop point blade is crafted from Sandvik 12C27 stainless steel, a high-performance Swedish alloy optimized for professional-grade sharpness, high toughness, and excellent corrosion resistance. The blade features a clean satin finish and deploys with silky-smooth action thanks to the integrated thumb stud and the IKBS™ ball bearing pivot system. The handle is constructed from lightweight, black glass-reinforced nylon (GRN), featuring a sophisticated texture that ensures a secure, high-traction grip even in wet conditions. Secured by a rock-solid liner lock and finished with a low-profile pocket clip, the Fidus is a refined EDC workhorse built for the long haul.
