Originally developed in response to restrictive knife laws in England that prohibited the carry of one-hand-opening lock-blade knives, Spydercos UK Penknife has become the go-to cutting tool for savvy knife users and travelers worldwide. As a member of Spyderco’s 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 elite expression of the UK Penknife features a blade crafted from premium CPM S110V stainless steel.- This material’s high volume of vanadium-rich and niobium-rich carbides give it exceptional wear resistance and corrosion resistance—both highly desirable qualities in a knife blade.
The blade of this UK Penknife is paired with an injection-molded fiberglass-reinforced-nylon (FRN) handle in a distinctive midnight blue color that identifies Spyderco’s elite CPM S110V series of knives. A deep-pocket, reversible wire clip supports left or right-side tip-up carry and ensures that this remarkable knife is always instantly accessible.
