The Spyderco Endura series first debuted over 25 years and blazed the trail as one of the first lightweight clip-carry folder knives. Now in its 4th generation, the Spyderco Endura 4 folder knife has continually improved upon itself--offering a broad range of variations and finishes to meet virtually every users taste, style and needs. This model, the C10FSK390, features a textured blue FRN (Fiberglass Reinforced Nylon) handle and a flat ground drop point blade in a satin finish. K390 MICROCLEAN, manufactured by Böhler-Uddeholm, is a high-quality steel produced by the particle metallurgy process. This advanced steel is extremely wear resistance and boasts high compressive strength, making for an outstanding blade for true steel connoisseurs. Each model in the Endura 4 family comes standard with a high strength lock back mechanism, stainless steel liners, and Spyderco's trademark round hole opening feature. This knife is an excellent everyday carry. 

Includes an ambidextrous 4-way positional pocket clip which allows for a tip up or tip down carry option on either side of the handle.
