Legal-Friendly Design. Elite Steel. A Non-Locking Folder That Doesn’t Compromise.

Originally developed to meet strict UK knife laws, the UK Penknife has become a global favorite for travelers and everyday users seeking a non-locking folder with premium performance. This elite version features CPM S110V steel for exceptional edge retention and corrosion resistance, paired with a lightweight FRN handle in Spyderco’s signature midnight blue.

With one-hand opening and a deep-pocket wire clip, it’s always ready—without raising eyebrows. The SLIPIT notch-joint holds the blade open without a mechanical lock, keeping it legal in more regions while delivering confident everyday cutting. The leaf-shaped blade pairs a full-flat grind with a satin finish for slicing efficiency, tip control, and reduced glare.
