Product Description

The CRESCENT RB-UB-50 is a 50-piece set of standard utility knife replacement blades manufactured from steel. These blades are designed for use in standard utility knives and are a direct replacement for worn or damaged blades on the job site. The set ships in an injection molded case, keeping blades organized and protected between uses. With overall blade dimensions of 5.2 inches in length, 2.8 inches in width, and 1.4 inches in height, these are sized to fit the most common utility knife platforms used by tradespeople across HVAC, electrical, plumbing, and general construction applications.

This blade set is well suited to residential and commercial job site use wherever a standard utility knife is part of the toolkit. Common applications include cutting insulation, stripping materials, scoring drywall, trimming vapor barrier, and general-purpose cutting tasks. The injection molded storage case makes it practical to carry a full supply of fresh blades throughout a workday, reducing downtime from dull blades mid-task.

Installation Notes

Blade replacement should be performed by a qualified tradesperson following the utility knife manufacturer's blade-change procedure. Always retract or remove the existing blade before accessing the blade storage compartment. Use the injection molded case or a dedicated blade disposal container to safely handle spent blades and avoid injury. Never attempt to change blades with the knife in an open or exposed position without securing the handle mechanism first.
