Spyderco's very first SLIPIT model, we created the UK Penknife after the United Kingdom prohibited the carry of folding knives with locking blades. It combines the key elements of our groundbreaking CLIPIT knives-a pocket clip for convenient carry and our Trademark Round Hole for easy, ambidextrous, one-handed opening-with an improved, nonlocking, notched-joint mechanism. This expression of the UK Penknife elevates the design even further with a blade crafted from our proprietary CPMSPY27 stainless steel. Its advanced, cobalt-enriched alloy composition offers excellent toughness, edge retention, and corrosion resistance. The full-flat-ground, leaf-shaped blade features a textured index-finger choil as an extra margin of safety and is housed in a lightweight handle built with fiberglass-reinforced-nylon (FRN) scales. The textured scales are injection molded in a signature blue color that identifies our CPM SPY27 family and include a deep-pocket wire clip that is reversible for ambidextrous tip-up carry. Founded in 1976, Spyderco is a leading innovator in high-performance knives, known for their signature round hole and ergonomic designs. Trusted by outdoor enthusiasts, first responders, and professionals, Spyderco uses advanced materials like CPM S30V and SPY27 steel to create durable, reliable tools. With a focus on precision and innovation, Spyderco continues to set the standard for quality in the knife industry.
