Slice Auto Retract Utility Knife

Utility knife features a long blade design to efficiently cut through thick materials, including triple-wall corrugated. 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. Ambidextrous design provides a comfortable grip for both left-handed and right-handed users. Easy, no-tool blade change allows you to simply replace dull blades without requiring any extra tools. Lanyard hole allows you to keep this unique tool in a convenient location to ensure it's always close at hand. Utility knife includes one double-sided, rounded-tip safety blade.
