Common Questions

Questions People Actually Ask About the CX-911

Is this box cutter safe for school use?

+

Yes, the CX-911 features a safe retractable blade mechanism with a safety lock. The blade fully retracts into the housing when not in use, ensuring safe storage in pencil cases or pockets without accidental exposure.

Can I use this for cutting heavy shipping boxes?

+

It is designed for lightweight, everyday tasks such as opening mail, cutting paper, and light packaging. For heavy multi-layer shipping boxes, we recommend a heavier 18mm utility knife with a thicker blade.
