9 mm Snap Off Knife

When a full-size cutter is overkill, reach for the Teng Tools 9 mm snap-off blade tool. It ships with two blades already included, so you can start working right out of the package and keep a spare ready for the moment the first edge loses its bite.

The narrow 9 mm blade width is purpose-built for detail cuts. Score drywall along a chalk line, trim peel-and-stick vinyl, slice packing tape on incoming deliveries, or clean adhesive residue off glass — every task where a wider blade would wander or damage surrounding material. The slim profile follows curves and contours that larger box knife alternatives simply cannot track.

At only 26 g, the plastic-bodied housing practically disappears in a shirt pocket or tool pouch. Despite the light weight, the body provides a secure grip during repetitive cuts so your hand stays comfortable through a full shift. When a blade segment dulls, snap it off to reveal the next sharp edge; when both blades are spent, the 9 mm snap-off format is one of the most common consumable sizes available, making restocking quick and affordable.

Whether you work in a warehouse, a workshop, or an office, this tool earns its place in your daily carry. Compact enough to travel with you, sharp enough to handle real work, and light enough to forget it is there until you need it.
