Cut plastic, paper, or tape with the Slice Safety Cutter Ring that is ideal for light cutting jobs. The zirconium oxide, micro ceramic blade has a finger-friendly edge, which is sharp for materials, but resistant to cutting skin. The ambidextrous design of the nylon ring will fit most index finger sizes, but the silicone liner is removable if your finger is larger than the ring. Also, the blade is non-conductive, non-magnetic, non-sparking, and chemically inert, so it will never rust.
