## Customer Reviews

### ⭐⭐⭐⭐⭐ Very safe box cutter
*by L***  on May 31, 2025*

I bought this box cutter because it was advertised as safer than your regular box cutter. Historically, I have often cut myself with standard box cutters. I have found this one very easy to use and I have not cut myself once. It even has a great design, which is much more usable than your standard one. I think I recall that when I bought it, the detailed description said that the blade (ceramic?) lasts much longer than the usual metal blades. I have actually purchased 2 of these because I keep them in different places in the apartment, and neither of the blades has gotten dull. Great product!

### ⭐⭐⭐⭐⭐ Ergo friendly
*by C***R on June 21, 2025*

Ergo friendly design. We open a lot of boxes and had a team member complaining of pain from holding the box cutter. I did a little research and decided to try this item. Much better! Only one they want me to order! Also love that the blade auto retracts so a bonus safety feature.

### ⭐⭐⭐⭐⭐ Great product!
*by J***N on June 23, 2025*

This has been one of my favorite purchases of the year! Recently started ordering more packages, and this has made it much easier to open without ruining the contents. With its lock, can’t hurt yourself. Also, with its build, it’s hard to miscut/open incorrectly!
