The STANLEY 10-099 is a retractable blade utility knife built for everyday cutting tasks on the job site. It features a patented interlocking nose design that holds the blade firmly in place during use, reducing blade wobble and improving cut accuracy. The three-position blade adjustment lets the user set cutting depth to match the material at hand. Blade storage is built directly into the handle, keeping spare blades accessible without requiring a separate pouch or case. At 0.34 pounds, the 10-099 is lightweight enough for all-day carry. Electricians, plumbers, HVAC techs, and general contractors reach for this knife as a standard hand tool.
This utility knife is suited for residential and light commercial work environments. Common applications include cutting insulation, stripping materials, scoring drywall, opening packaging, and trimming sheet goods. The retractable blade design makes it practical for trades where a knife stays clipped to a belt or stored in a tool bag throughout the shift.
Designed as a standard retractable utility knife compatible with common replaceable utility blades used across residential and commercial trade applications.
No installation is required for this hand tool. When changing blades, retract the existing blade fully before opening the handle storage compartment. Always use blade-change practices appropriate to your employer safety program and applicable OSHA hand tool guidelines. Dispose of used blades in a puncture-resistant sharps container.
