This safety box cutter pairs an ergonomic J-hook handle with a patented ceramic blade that stays sharp 11 times longer than steel. The 100 percent zirconium oxide blade is non-sparking, non-magnetic, chemically inert, and will never rust. The auto-retractable handle retracts the blade the moment it loses contact with the cutting surface, reducing injury risk. Suitable for single- and double-walled corrugated cardboard, the ambidextrous design includes one double-sided rounded-tip safety blade.
