In 1990, Spyderco revolutionized the knife market with the introduction of two groundbreaking models the Delica and Endura. These lightweight, one-hand open pocketknives became instant favorites, setting a new standard for performance and affordability. Over the years, they have remained our top sellers, continually evolving to meet the demands of our customers. Driven by our commitment to innovation and performance, we are excited to introduce the Endura 4 Lightweight with a blade crafted from K390 steel. Manufactured by Bohler-Uddeholm using the particle metallurgy process, K390 MICROCLEAN is a cutting-edge cold work tool steel known for its exceptional wear resistance and high compressive strength. Originally developed for industrial cutting, blanking and punching operations, K390's advanced alloy composition also ensures ease of machinability and reliable heat treatment. These unique attributes make K390 an ideal choice for discerning enthusiasts seeking the ultimate in blade performance.
