The STANLEY 10-817 is a snap-off cartridge knife designed for scoring, cutting, and trimming tasks in trade and maintenance environments. The die-cast aluminum handle measures 8 inches overall and provides a durable, professional-grade grip. The snap blade measures 5.5 inches in length and features 7 snap points, allowing the user to break off a dull segment and expose a fresh cutting edge without changing the full blade. Four blades are included in each unit. This knife is a standard tool for HVAC installers, electricians, plumbers, and general maintenance technicians who need a reliable utility cutting tool on the job.
The STANLEY 10-817 is suited for residential and light commercial trade work. It fits naturally in an electrician or HVAC technician's tool pouch for cutting wire insulation, duct board, vapor barrier, pipe wrap, fiberglass batt, and general jobsite materials. The compact snap-blade format makes it practical for confined spaces and repetitive cutting tasks where blade sharpness matters. The included four-blade supply means less downtime searching for replacements mid-job.
Replacement blades for this knife are the Stanley 11-325T. Designed as an OEM-style snap-blade knife compatible with standard snap-off blade cartridge formats used across trade applications.
No installation is required for this hand tool. Before snapping off a blade segment, retract the blade fully or point it away from personnel to avoid injury. Dispose of snapped blade segments in a puncture-resistant sharps container per jobsite safety practices. Inspect the blade lock mechanism before each use to confirm the blade is fully secured prior to cutting.
