Police 4 Lightweight K390 – Blue FRN

The Spyderco Police 4 Lightweight K390 combines the classic profile of one of Spyderco’s most iconic designs with modern materials and a lightweight construction. Developed through decades of user feedback and refinement, it delivers excellent ergonomics, reliability, and cutting performance.

The fiberglass-reinforced nylon (FRN) handle significantly reduces weight while maintaining excellent strength. Its textured surface provides a secure, non-slip grip, and the design remains fully ambidextrous for versatile everyday use. The distinctive blue handle color identifies models equipped with the premium K390 blade steel.

The blade is crafted from Böhler K390 tool steel, known for outstanding edge retention, high wear resistance, and exceptional durability. Its full flat grind ensures excellent slicing performance across a wide range of tasks. A reliable lockback mechanism secures the blade firmly during use.

A black stainless steel pocket clip allows versatile carry options, including tip-up or tip-down and left- or right-side carry.
