Originally introduced in 2009, the Urban™ is a proud member of Spyderco's unique SLIPIT™ class of folding knives. This hybrid breed combines our revolutionary Trademark Round Hole™ and pocket clip with an enhanced notch-joint spring mechanism to create legally permissible non-locking folding knives that offer the advantages of one-hand opening and convenient clip carry.
This limited edition Sprint Run expression of the Urban Lightweight supercharges this time-tested design with ultra-high-performance K390 MICROCLEAN® blade steel. Manufactured by Böhler-Uddeholm, K390 is an advanced cold work tool steel produced by the particle metallurgy process. Its sophisticated alloy mix was specifically developed to provide the extreme wear resistance and high compressive strength needed in industrial cutting, blanking, and punching operations. Amazingly, its exceptionally fine, homogeneous microstructure also makes it readily machinable and easy to heat treat. As a blade steel, these qualities translate to outstanding edge retention and excellent toughness.
K390's advanced alloy composition includes nearly 2.50% Carbon, as well as Chromium, Molybdenum, Manganese, Vanadium, Tungsten, Cobalt, and Silicon. K390 is a true tool steel, however, not a stainless steel, so it must be properly maintained to prevent corrosion.
This one-of-a-kind expression of the Urban Lightweight features a distinctive gray fiberglass-reinforced-nylon (FRN) handle and a reversible deep-pocket wire clip. Combining the very best of socially friendly design and high-performance blade steel, this distinctive Urban Lightweight Sprint Run is one of the most remarkable and collectible SLIPIT knives we've ever produced.
