The STANLEY 11-040 is a replacement utility knife blade designed for use with the STANLEY 10-049 utility knife. These blades deliver clean, controlled cuts through a wide range of trade materials including insulation, vapor barrier, roofing felt, duct wrap, pipe insulation, and general-purpose sheeting. Sold individually, they are a standard consumable item for HVAC technicians, plumbers, electricians, and general contractors who rely on utility knives throughout the workday. Lightweight at 0.02 pounds per blade, the 11-040 is easy to stock in a service van or tool bag and swap out quickly on the job.
These replacement blades are suited for light commercial and residential trade applications wherever a sharp, reliable utility blade is required. The 10-049 knife is a common hand tool across multiple trades, making the 11-040 blade a standard restocking item for shop supply and field kit management. The minimum order quantity is 10 blades, making them practical to keep on hand for ongoing service work.
Designed as a replacement blade for the STANLEY 10-049 utility knife.
Blade replacement should be performed by a qualified tradesperson using the blade-change mechanism built into the knife handle. Always retract or remove the blade before changing it, and never handle exposed blades with bare fingers. Dispose of used blades in a puncture-resistant sharps container or dedicated blade disposal unit in accordance with jobsite safety protocols.
