Mini cutter features a versatile design to work as well as a safety box cutter as it does a pocket knife or kitchen multi-tool. The advanced ceramic material is rustproof, nonconductive, antimagnetic and won't spark. The slow-to-dull blade starts at an effective sharpness and retains its safe cutting edge for up to 11 times longer than steel for consistently smooth cuts again and again. Auto-retractable blade stays out of harm's way when you're not using the knife for safe storage. Keyhole and built-in magnet allow you to keep this unique tool in a convenient location to ensure it's always close at hand. Easy, no-tool blade change allows you to simply replace dull blades without requiring any extra tools.
