OKNIFE Ceramic Utility Blades Black (10 Pack)

OKNIFE Ceramic Utility Blades in black bring zirconium oxide bite to your everyday cutter, with a brushed finish that looks as clean as it slices.

• Zirconium Oxide Ceramic — Holds an edge far longer than steel, shrugs off rust entirely, and stays chemically inert so the blades are safe around food, packaging, and moisture.
• Universal Trapezoid Fit — Standard utility blade shape drops into the Oknife Otacle U1, U1 Pro, U1 Ultra, and most other box cutters and utility knives you already own.
• Non-Conductive and Non-Magnetic — Safe pick for electronics work, insulation jobs, and clean-room tasks where stray current or magnetism causes problems.
• Brushed Black Finish — Precision flat-ground surface looks sharp, wipes clean in seconds, and fights staining better than typical ceramic blades.

Oknife UB2C Ceramic Blades

Oknife builds gear under the same Olight family banner, with a focus on clean industrial design and materials that punch above their category. The UB2C blade was developed alongside the Otacle utility knife platform but uses a standard trapezoid profile, so it fits most box cutters on the market. Ceramic is the headline here, prized for hardness, corrosion resistance, and edge life that steel cannot match. Keep in mind ceramic is brittle, so prying or twisting will chip the edge.
