The Diplomat Slice 10554 auto-retractable ceramic safety blade responds to customer demand for a long blade to cut through thick materials, including triple-walled corrugated. Designed for cutting a variety of materials from clamshell packaging to triple-walled cardboard, the Slice utility knife combines strength with superior safety features. It comes with a rounded tip ceramic safety blade that lasts up to 10x longer than steel and is safer to handle. Ambidextrous, rotate the blade edge quickly and without tools to adjust for right or left-handed use. As with all our ceramic blades, the retractable utility knife blade is non-conductive, chemically inert, and never rusts. Replacement Blade SKU 25044098
