Originally released in 1994, the Dragonfly was one of Spyderco’s original lightweight knives and helped to introduce the use of injection-molded fiberglass-reinforced-nylon (FRN) handles. Manufactured by Böhler-Uddeholm, K390 MICROCLEAN® is a state-of-the-art cold work tool steel produced by the particle metallurgy process. Its advanced alloy mix was specifically developed to provide the extreme wear resistance and high compressive strength needed in industrial cutting, blanking, and punching operations. Despite its toughness, its exceptionally fine, homogeneous microstructure also makes it readily machinable and easy to heat treat. Collectively, these qualities make K390 an outstanding blade material for true steel connoisseurs.
