The CRESCENT RB-UB-5 is a set of five standard utility knife replacement blades made from steel. These blades are designed for use in standard utility knives commonly found in HVAC, plumbing, electrical, and general trade work. Each blade measures 2 inches in overall length, 0.8 inches in width, and 0.2 inches in height. The set ships in an injection molded case for safe handling and storage between uses. Tradespeople who rely on utility knives for cutting insulation, sheathing, tape, and other materials will find these blades a straightforward stock-up item.
These replacement blades are suited for residential and commercial job sites wherever a standard utility knife is in regular use. Common applications include cutting duct insulation, vapor barrier, electrical cable sheathing, and packaging materials. The injection molded storage case keeps unused blades contained and reduces the risk of accidental contact during transport in a tool bag or service vehicle.
Designed as standard utility knife replacement blades compatible with most conventional utility knife handles that accept standard trapezoidal-style blades.
Blade replacement should be performed by a qualified tradesperson following the knife manufacturer's blade-change procedure. Always retract or remove the existing blade before loading a new one, and never handle loose blades without appropriate cut-resistant gloves. Dispose of used blades in a puncture-resistant sharps container in accordance with local jobsite safety requirements.
