The Spyderco Police 4™ Lightweight CPM® SPY27® represents the evolution of an icon. Building on the legendary Police design, this fourth-generation model incorporates modern materials and engineering to deliver outstanding performance in a lightweight, easy-to-carry package.

At its core is a 4.38-inch CPM SPY27® stainless steel blade, exclusive to Spyderco and made in the USA. SPY27 supercharges VG-10 steel with niobium, nitrogen, and enhanced carbon, molybdenum, and vanadium content. The result is a blade that offers exceptional edge retention, toughness, corrosion resistance, and ease of sharpening—perfect for professional use and serious everyday carry.

The blade features a full-flat grind and a satin finish for smooth, efficient cutting. A lightweight cobalt blue FRN (fiberglass-reinforced nylon) handle houses skeletonized stainless steel liners and a sturdy back lock mechanism, ensuring strength without unnecessary weight. A four-position pocket clip provides ambidextrous tip-up or tip-down carry, making this knife adaptable for any user.

Whether you're a Spyderco collector or an EDC enthusiast, the Police 4 Lightweight in SPY27 steel sets a new standard for performance, ergonomics, and carry comfort.
