Review: Sharp, Reliable, and Great Value for Everyday Cutting Tasks - The REXBETI 12-Pack Utility Knives are a great value and work exactly as expected. The blades are sharp right out of the box and cut through cardboard, cartons, and packaging with ease. The retractable design feels solid and locks securely in place, which adds a nice level of safety while using them. I really like having a 12-pack—it’s perfect for keeping one in multiple rooms, the garage, toolbox, or vehicle. The handles are lightweight but sturdy, and the 18mm blades provide clean, controlled cuts without snagging. These box cutters are practical, dependable, and affordable. If you go through a lot of packaging or just want reliable utility knives on hand, this set is a smart buy.
Review: ABSOLUTELY LOVE THESE. Can't say enough good about them for light duty cutting. - ABSOLUTELY LOVE THESE!! Can't say enough about them. I bought a box of these and started putting them everywhere; in the junk drawer, in the garage, in the night stand, one in each vehicle, by my chair in the living room. Just a nice utility knife to have. Please know, I use them for light duty. I use them to cut cardboard, open packages, they were great for Christmas morning unwrapping. I recently bought a couple "Case Club" (not sponsored) gun cases. These worked GREAT to cut out the foam inserts; able to use them when the blade was fully extended. BUT, I can see where there might be issues if you want to use them for heavy duty use. The listing says "Office and Home use". I think the reference to "Office and Home use" is accurate. I don't know how long they might last with some of the items listed in the details section of the listing: leather, roofing, and linoleum. From personal experience, I can see where they might dull quickly with those items. I would probably go with the traditional box cutter with higher end blades for those items. I also have not snapped off any of the blades to keep them sharp. I am trying to see how long I can go with the end before snapping it off. That said, I always retract the blade after using the knife. I do find that when I extend it, it often extends further than I really need. It still works well, but that does cause the other segments to be exposed to wear when cutting. That will affect the sharpness of the other blade segments when I finally do start snapping them off. I know that this is my doing because I just quickly extend the blade without taking the time to just expose the first one or two segments. As far as the locking mechanism goes, I have so far had good luck with it holding in place. I like the grip. I can see where some might not like the contour. I have fairly large hands and I can easily hold and control the blade. I saw that some had issues with construction of the knife not holding up. I have not had any issues with that so far. Quick summary: Seem to work well for light duty cutting. Light weight. Fits this users hand well. I believe they are a good product for the price; at the time of purchase less than a dollar each.

## Questions & Answers

**Q: Except cutting boxes, what else it can do for me**
A: Bring you coffee to bed  every morning to bed, make you breakfast, cut your lawn.

**Q: Actually you will receive 12 box cutters, not 1, right?**
A: Yes its a case of 12

**Q: How's it working for you so far?**
A: We are using them to cut Insofast, a product for insulating basements. Insofast is a  2" thick foam panel. The knife cuts through it well, but the blade is a bit loose when fully extended. In other words, it is an inexpensive knife that works and disappoints at the same time. I would not use it for precision cutting.

**Q: Are the blades sharp?**
A: I am amazed how sharp these blades are! These blades (including the quality housing) are easily 100% better than most of the cheap box cutters sold on Amazon. Well worth the extra $4 to upgrade. I got my first box and immediately saw the difference... So much so, I bought a second box a week later.

### ⭐⭐⭐⭐⭐ Very inexpensive and work great.
*by L***R on November 9, 2025*

These things are great. Very easy to use, open and close. and can "lock" them to prevent the blade from moving. For the price...an excellent buy. I placed them all over the house and garage.. Wish I had found these years ago.
