For those who prefer or require non-locking folding knives, we are excited to offer the exceptional performance of our proprietary CPM SPY27 steel. To meet this demand, we proudly present a version of our revolutionary UK Penknife, now featuring a blade made from CPM SPY27. As the first member of Spyderco's SLIPIT family, the "UKPK" was the pioneer in combining the convenience of top-of-the-pocket clip carry and one handed opening (via our Trademark Round Hole) with a socially and legally friendly notched-joint non-locking mechanism. This updated version retains all the key features of the original, while adding a full-flat-ground, satin-finished CPM SPY27 blade and signature cobalt blue peel-ply textured G10 handle scales.

Satin-finish CPM SPY27 steel blade for high-performance edge retention
Cobalt blue G10 handle combines durability with a striking look
Thumb pull design for easy, controlled blade access
Equipped with a pocket clip for easy and secure carry
Slip joint design for easy use without a locking mechanism
Proudly made in the USA with premium materials
