Box Cutter, Auto-Retract, 7/10"Wx6-7/10"Lx3-2/5"H, GYGN

Box cutter features an ergonomic, J-hook handle that takes safety to a new level to help keep your fingers safe. 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. Retractable blade prevents you from accidentally leaving the blade exposed for safe use. 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. Box cutter is suitable for single-walled and double-walled corrugated materials.
