This Irwin 1774106 is a Quick-Change Retractable Utility Knife, a core tool for any job site.

• Quick-Change Mechanism: This is the defining feature of the tool. It allows you to swap out dull blades for new ones instantly at the push of a button—no screwdrivers or housing disassembly required. This significantly minimizes downtime when you are in the middle of a repetitive cutting task.

• Retractable Design: The ability to fully retract the blade into the handle ensures safety when the tool is carried in a pocket or stored in a tool belt, and it protects the blade edge from damage when not in use.

• Ergonomics and Durability: Irwin builds these with a heavy-duty, reinforced metal body designed to withstand drops and high-pressure cutting. The grip is typically contoured to provide a secure hold, even when your hands are oily or wearing gloves.
