Description The Police is one of the original models in the Spyderco range. The philosophy of constant evolution has led to the Police 3 and now the Police 4, which features a Böhler K390 blade with a SpyderEdge serrated edge. Skeletonised stainless steel liners under the textured blue FRN scales keep the weight in check and offer maximum stability. The four-position convertible clip and the backlock also make the knife completely left-hand compatible.
