SPYDERCO C11FSK390 DELICA 4 FOLDING KNIFE – K390 STEEL – BACK LOCK – MADE IN JAPAN – SPYDER EDGE BLUE FRN HANDLE
Spyderco Delica 4 K390 – Industrial Steel, Everyday Precision
The Delica 4 Lightweight K390 takes one of Spyderco’s most iconic EDC designs and supercharges it with Bohler-Uddeholm’s K390 MICROCLEAN tool steel—a high-performance alloy engineered for extreme wear resistance and edge retention. Originally developed for industrial cutting and punching applications, K390 offers steel connoisseurs a blade that stays sharp through the toughest tasks.
This version features a fully serrated edge for aggressive cutting power, a full-flat grind for slicing efficiency, and a satin finish for understated style. The lightweight blue FRN handle is textured for grip and houses a reliable back lock mechanism. A four-position stainless steel clip ensures ambidextrous tip-up or tip-down carry. Made in Seki City, Japan, this Delica is built to work hard and carry light.
