This thing is amazing at taking apart packaging. Obviously it's sold as a cardboard knife and that's really where it excels, destroying cardboard almost like it isn't there. I wouldn't call it a knife, though — it's more like a miniature saw and works more like a saw than a knife. It's unlikely to cut you so it's pretty safe unless you happen to be made of packaging. It also seems to have stayed sharp since I bought it, despite cutting apart literally hundreds of boxes. It does mean that I don't tend to have spare boxes lying around, now, though. The temptation to simply tear something apart with this once it arrives is simply too great to resist.

The amount of Amazon parcels I receive (almost daily) I needed a decent tool to open the boxes and to cut them up for recycling after. This is the best possible knife I have found for the job! It's safe due to its serrated edges, so not sharp enough to the touch to cause injury, but is 100% sharp enough on cardboard. Making it exceptionally easy even on very thick board. Plastic handle but rigid sturdy blade. I am unsure how long this will last but I have had it for about a year now and it still works well. I bought a couple of extra just in case it disappears from Amazon in the future as I haven't found anything as good yet.

Great little cardboard cutting tool cuts it perfect without the chance of cutting hands

Saw this go viral on twitter about how well it cuts cardboard and it didn’t disappoint! Debated buying some friends them as it’s so helpful.

This is one of those bits of kit you don’t know you need. Trust me, you do! Mine lives in the kitchen and is used to slice cardboard, open packets, slit sellotape and so much more. In fact it has become an invaluable tool that I wouldn’t want to be without. Best of all, it’s much safer to use than a box cutter and package contents are unlikely to be damaged by accident. I have been using mine for months and it is still as good as new. Doesn’t need sharpening and tough as old boots. You may have noticed that I’m a fan, I’ve even purchased one for my son who is as pleased as me.

Got it for like a month and seems to work well to open up boxes and cut them up to fit in my recycling bin. When I first opened it I felt like it was a bit short but I got used to it. It's really more of a saw than a knife so it will do a bit more mess than a regular knife when cutting cardboard but you will not ruin your knives and won't have to sharpen them as often.

Bought this little gadget to make life easier when getting cardboard box deliverys, which is all deliverys Almost! breaking down boxes is a nightmare! I've just had a delivery of a treadmill and the box it came in must have been 1/2 inch thick 😳, however this little gadget knife went through it like butter. This has been my best purchase of 2025 for very little cost.
