# Spyderco UK Penknife Cobalt Blue Lightweight

Originally designed to comply with restrictive British knife laws, the UK Penknife has developed a cult following among pocketknife enthusiasts worldwide. The original SLIPIT model, it combines one-hand opening via our Trademark Round Hole with the convenience and accessibility of clip carry. This unique expression of it showcases a full-flat-ground blade crafted from CPM SPY27, a cobalt-enriched particle metallurgy stainless steel developed specifically for Spyderco. The blade is complemented by fiberglass-reinforced-nylon (FRN) handle scales molded in a distinctive cobalt blue that is one of the signature colors of our family of knives featuring this proprietary steel.
