Common Questions

Questions People Actually Ask About the CX122

Is this utility knife suitable for cutting boxes?

The CX122 is a 9mm light-duty utility knife. While it can handle single-layer corrugated cardboard, it is not recommended for heavy multi-layer shipping boxes. For heavy-duty box cutting, we recommend using an 18mm knife like the CX68 or CX201.

What should I do when the blade gets dull?

Utility knife blades are segmented with pre-scored lines. When the tip becomes dull, simply snap off the worn segment along the scored line to reveal a fresh, sharp edge and keep cutting.

Is it safe for students to use?

Yes, it is designed with a retractable blade and a secure safety lock that prevents accidental blade deployment. The small, lightweight body makes it easy to control safely for school projects and handicrafts.

How can I get a free sample?

Before placing an order, we can send you a sample of any in-stock model. Simply let us know which specific model you'd like to test.
