OKNIFE Ceramic Utility Blades Black (10 Pack) UB2CB

OKNIFE Ceramic Utility Blades in black bring zirconium oxide to your box cutter, holding a keen edge far longer than steel and shrugging off rust for good. The brushed black finish wipes clean after messy work.

• Brushed Black Finish — A precision flat-ground surface gives each blade a low-glare black look, cuts drag as it slices, fights staining, and wipes down in seconds after sticky or greasy work leaves a mess behind.
• Zirconium Oxide Ceramic — Holds a sharp edge far longer than steel and never rusts, while the inert ceramic stays safe around food, packaging, and moisture. It is hard but brittle, so skip prying or twisting, which can chip the edge.
• Non-Conductive & Non-Magnetic — Ceramic carries no charge and holds no magnetism, so these blades suit electronics work, insulation jobs, and clean-room tasks where stray current or loose metal shavings cause trouble.
• Universal Trapezoid Fit — The standard trapezoid profile drops into the OKNIFE U1, U1 Pro, U1 Ultra, and Otacle Pro, along with most other box cutters and utility knives you already own, so no special holder is needed.

OKNIFE builds knives, tools, and EDC gear under the Olight family, and these ceramic blades keep your utility knife cutting long after a steel blade would quit.
