Spyderco Endura 4 Lightweight Wharncliffe K390 Folding Knife C10FPWK390

Spyderco has always taken great pride in pushing the boundaries of performance by offering exotic blade steels in its knives. With that spirit in mind, they proudly announce a range of best-selling models featuring blades made from K390. Manufactured by Bohler-Uddeholm, K390 MICROCLEAN is a state-of-the-art cold-work tool steel produced using the particle metallurgy process. Its advanced alloy blend was specifically developed to provide extreme wear resistance and the high compressive strength required for industrial cutting, blanking, and punching operations. Despite its toughness, its exceptionally fine, homogeneous microstructure is also easy to machine and heat treat. Together, these properties make K390 an outstanding blade material for true steel connoisseurs. Spyderco is proud to feature it on some of its most popular models, which also stand out with distinctive blue handles.

Note: K390 is a high-performance stainless steel that can rust if not properly cared for. Always clean and dry the blade after use, and apply oil or other corrosion-preventive products when needed.
