Black Decker 10-778 Fatmax Retractable Utility Knife

Product Description

The BLACK DECKER 10-778 is a FATMAX retractable utility knife measuring 6.625 inches in overall length. Built for tradespeople who need reliable cutting performance on the job, it combines a hardened blade with an ergonomic soft-touch grip for controlled cuts across a wide range of materials. The retractable blade mechanism keeps the edge protected during transport and storage, reducing the risk of accidental contact. A built-in blade wiper removes excess debris from the blade as it extends, maintaining clean, consistent cuts throughout the workday.

This utility knife is suited for general trade use including HVAC duct work, electrical cable stripping, insulation scoring, roofing material trimming, and general construction tasks. The compact 6.625-inch body fits comfortably in a tool pouch or apron pocket, making it practical for technicians and installers who carry multiple tools on a service call. Integrated blade storage inside the handle allows for quick blade changes with minimal downtime.
