Safety and savings aren't rocket science; it's made simple with Slice™ cutters and blades! Slice™ ceramic blades last up to 10x longer than steel. Blades are safer than traditional metal blades yet they cut through corrugated like butter! They are double sided with round edges for safety. The chemically inert zirconium oxide ceramic blade never rusts. Blades are non-corrosive, non-conductive, non-magnetic and non-sparking. Oil-free finish makes these blades perfect for use in clean rooms. Thicker blades make it easier and safer to handle.
