Description As a tribute to the police forces in the USA, Spyderco presents the knives of the Thin Blue Line series. The popular Rescue 3 Lightweight has a spacer in a bright blue, which stands out against the black FRN handle. The blade is made of solid VG-10 with a serrated edge. The typical Spyderco thumb hole, the solid backlock and the four-position convertible clip make the knife extremely suitable for everyday use.
