This version of Spyderco’s trendsetting UK Penknife™ is ideal for knife enthusiasts seeking extreme cutting performance and edge retention in a non-locking format. The original member of our unique SLIPIT™ line of knives, it combines the convenience of clip carry and one-hand opening with a socially friendly notch-joint mechanism that helps hold the blade safely open during use, but does not mechanically lock it. This unique expression of the UK Penknife features a blade crafted from premium CPM® S110V®—a high-alloy martensitic stainless steel produced by the Crucible® Particle Metallurgy (CPM) process. This material’s high volume of vanadium-rich and niobium-rich carbides give it exceptional wear resistance, while its generous chromium content ensures impressive resistance to corrosion. The full-flat-ground, leaf-shaped blade takes full advantage of these properties to offer outstanding edge geometry and cutting performance. It is paired with an injection-molded fiberglass-reinforced-nylon (FRN) handle that proudly boasts the distinctive midnight blue color our elite CPM S110V series of knives. A reversible deep-pocket wire clip supports left or right-side tip-up carry and ensures that this remarkable knife is always instantly accessible.
