Slice #S5 ceramic utility knife replacement blades deliver a razor-sharp, double-sided cutting edge that fits most standard utility knife handles. Made from zirconia ceramic, these blades are non-conductive, non-magnetic, chemically inert, and will never rust — lasting up to 10x longer than comparable steel blades, with each single blade equivalent to approximately 20 metal blades.
Each pack contains two rounded-tip blades measuring 63 x 19 x 0.8 mm (2.5 x 0.75 x 0.3 in), weighing just 3 g each. The rounded tip design reduces accidental punctures and cuts, making these blades a safer alternative to traditional metal utility knife blades for cutting tape, packaging, film, and other materials.
