12-Pack Utility Knife, Retractable Box Cutter for Cartons, Cardboard and Boxes, 18mm Wider Razor Sharp Blade, Smooth Mechanism, Perfect for Office and Home use | Razor Sharp Snap-Off Blade, Smooth Sliding Mechanism, Durable Cutter Knife for Cartons, Cardboard, Boxes, Office and Home

Such a good value. So sharp, they seem to last forever. I use them in my garden sometimes, so I do know they will rust in a second, but inside they are awesome. Easy to snap the. Tip off for a new blade and the locking feature is solid. Very good product, and I rarely give good reviews.

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.

I am very happy with this REXBETI 12-pack utility knife set. The 18mm blades are extremely sharp and make cutting through cardboard boxes, packaging tape, plastic, and other materials quick and effortless. The retractable mechanism is smooth and reliable, allowing easy blade adjustment while maintaining safety. One of my favorite features is that the pack includes 12 knives, making it easy to keep one in the office, garage, workshop, or around the house. They feel durable, comfortable to hold, and perform very well for everyday tasks. For the price, this is an excellent value and a must-have for anyone who frequently opens packages, moves boxes, or works on DIY projects. Highly recommended!

Nice knifes, little on the flimsy side but function great, and price was right

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.

Blades are sharp as expected. Housing is sturdy..nice disposable set.

I really like this 12-pack of REXBETI utility knives — we keep them all over the garage, office, and kitchen so there’s always one within reach. They’re lightweight but sharp, and they make opening Amazon packages and breaking down recycling quick and easy. For the price, it’s a great value to have multiple knives in convenient spots so you’re never searching for one. They cut cleanly and hold up well for everyday tasks. Pros: • Great value for a 12-pack • Sharp blades that open packages easily • Useful for recycling, crafts, and everyday tasks • Lightweight and easy to keep everywhere (garage, office, kitchen) Cons: • Not as heavy-duty as metal-bodied knives • Plastic handles can feel light, but they get the job done

Good value. Easier to use due to to its larger size. Retracts/extends well.

I am forever misplacing my utility knives. Every time I use it, it seems to disappear. Then I spend forever looking for one just for a simple task. Now I have 2 in every room and always have one at hand.
