The MODIFIED Spyderco Delica 4 Lightweight K390 Knife is a new iteration of a classic everyday carry that features an ACID STONEWASH 2.90 inch wharncliffe blade made of Bohler-Uddeholm K390 tool steel, .098 inch thick. The ACID STONEWASHED blade has a full flat grind, a notched thumb ramp for secure grip, and the Spyderco Hole for ambidextrous one hand opening. The blue FRN (fiberglass nylon resin) handle has been given a black Rit Dye fade starting from the pivot. The dye steadily fades toward the acid stonewashed pocket clip which has also been heat colored. All hardware contrasts nicely with this bronze heat color. The Spyderco Delica 4 Lightweight K390 Knife has an overall open length of 7.15 inches, and it weighs 2.4 ounces. Made in Japan.
From the 2020 Spyderco Reveal 5 product guide: In 1990 Spyderco shook things up by introducing two knives, the Delica and Endura. First of their kind on the market, both folders opened up the knife market to lightweight performance, one-hand open pocketknives that just about everyone could afford. They settled as our top two bestsellers and their improvement hasn't slowed since.
We've always taken great pride in our efforts to push the envelope of performance by offering exotic blade steels in our knives. With that spirit in mind, we are proud to offer the Delica 4 Lightweight with a blade crafted from K390.
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.
