Spyderco Knives Spyderco Manbug Lightweight Folding Knife 1.97″ K390 – MFPK390

Spyderco has always taken great pride in its efforts to push the envelope of performance by offering exotic blade steels in their knives. With that spirit in mind, they are proud to announce that they are offering a number of best-selling models with blades crafted from K390. Manufactured by Bohler-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. Spyderco is proud to feature it on some of their most popular models, which are also distinguished with distinctive blue-colored handles.
