The Spy-DK is based on the platform of Spyderco's revolutionary UK Penknife, but specially modified to allow it to conform with Danish knife laws. Its blade is full-flat ground from Böhler-Uddeholm's premium N690Co stainless steel, but its length is reduced to 68mm (2.69 inches). The Trademark Round Hole clearly identifies it as a Spyderco knife and provides a handy purchase for two-handed opening, but the hole is purposely small to prevent one-handed blade-opening methods. Its stout notched-joint mechanism is also powered by a strong spring that helps hold the blade securely in the open and closed positions, supporting its safe use as a cutting tool while precluding one-handed opening.
The Spy-DK's lightweight handle is constructed of injection-molded fiberglass-reinforced-nylon (FRN) scales attached directly to the stainless steel back spacer/spring. The molded checkered pattern on the scales and a textured index-finger choil at the juncture of the blade and handle ensure a secure grip and allow the user's index finger to serve as a natural stop to prevent unintentional closure during use. A reversible deep-pocket wire clip provides both left and right-side tip-up carry, keeping the knife accessible for immediate use while naturally blending with virtually any color of clothing.
Although created to conform with Danish knife laws, the Spy-DK's highly functional design and socially friendly demeanor make it a perfect choice for knife users everywhere. It combines convenient clip carry and a purposeful two-hand-opening into a design that redefines the non-locking pocketknife.
