Film cutters are safe and easy to use with no exposed blades. They're strong and lightweight and are suitable for slitting bubble wrap, stretch film, foam and all polythene material. Turn the knife over and the tape slitter will open cartons without risk of damaging the contents inside. This safety film cutter comes with a keyring so that it can be attached to a retractable lanyard or YoYo for convenience. You'll never loose your film cutter again!
