WHY IT'S PERFECT FOR YOU

The 10-778 is a no-fuss utility knife for everyday site and workshop cutting — retractable blade, lockable position, solid grip, and spare blades already in the handle. It handles scoring and cutting cardboard, carpet, insulation, roofing membrane, and wallboard cleanly.

The blade retracts fully for safe carry in a tool belt or toolbox, and the lock holds it in position once extended so it doesn’t creep back under load. Small enough for everyday carry, well-balanced, and ready for repeated daily use.
