This Stanley 11-911 is the industry-standard "1991" replacement utility blade. It is one of the most recognizable and widely used blades in the construction and painting trades.

• Classic Design: These are the traditional regular-duty, two-notch straight blades. They are designed to fit almost every standard fixed-blade or retractable utility knife ever made.

• Versatility: While they aren't the heavy-duty bi-metal blades, they are the go-to choice for lighter tasks—opening boxes, cutting light paper, scoring cardboard, or general shop use.

• Cost-Effectiveness: Because they are standard carbon steel, they are an economical choice for tasks where you might go through blades quickly and don't need the extreme durability of high-end bi-metal or specialty alloy blades. Keeping a supply of these on hand is essential for general job-site maintenance and cleanup.
