The fourth-generation Police 4 Lightweight combines the classic features of the original Police design with the benefits of lightweight injection-molded handle construction. Raising the bar even further, this expression elevates the design with the American-made CPM SPY27 steel blade. Exclusive to Spyderco, CPM SPY27 enhances the cobalt-enriched chemistry of VG-10 stainless steel with niobium, nitrogen, and increased volumes of carbon, molybdenum, and vanadium to deliver an exceptional balance of edge retention, toughness, corrosion resistance, and ease of sharpening. This knife's satin-finished, fully flat PlainEdge blade takes full advantage of these properties and is paired with a lightweight, fiberglass-reinforced nylon (FRN) handle molded in distinctive cobalt blue, one of the signature colors of our elite SPY27 knife family. The handle also houses the knife's sturdy rear locking mechanism, skeletonized stainless steel liners, and a four-position pocket clip that lets you choose whether to carry it on your left or right side, with the tip pointing up or down.
