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

The CANARY Corrugated Cardboard Cutter Handsaw is an absolute beast for breaking down boxes—hands down better than your average utility knife. Its serrated edge is specifically designed to glide through thick, layered cardboard with ease, making quick work of even the toughest boxes without snagging or dulling. Unlike regular knives that often require excessive force or multiple passes, this cutter saws smoothly through corrugation, reducing hand strain and saving time. Plus, its ergonomic handle provides a solid grip, making it safer and more comfortable to use for extended sessions. If you’re tired of fighting with flimsy blades or box cutters that give up halfway through a job, this tool is a game-changer. Perfect for decluttering, moving, or breaking down boxes for recycling—it’s a no-brainer for anyone who deals with cardboard regularly.

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.

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.

A great Box cutting tool, my only gripe is that i wish it had a slightly pointier end as it is sometimes hard to get it in and under tape. It does works a treat, i love the saftey aspect as its not sharp that it can cut your fingers but super sharp to easily cut through card board. My other little gripe you get the flimsiet thinnest and i mean super thin protective sleeve, like seriously it may as well not even be included at this pooint. It is so so thin it takes forever to open it to put the blade in when finished. If you are going to include a protective sleeve which i believe is necessary, make it a half decent one at least. Bar this the Canary corrugated Box Cutter is brilliant. Recommended

Non taglia ma sega, l'ho usato per segare degli imballaggi duri di multistrati, ha funzionato bene le prime volte ma sega meno dopo .

En av mina absoluta mest oväntade bästa köp! Sågar upp alla pappers kartonger och grejen är att den inte är vass som en vanlig kniv så det går att ha den i fickan.

Love it, amazing tool to open cardboard, EPE packaging, amazon boxes and whatever packaging that stands in its way. The length makes it easy to reach far as well. Just have to be cautious not to cut too deeply to damage the product inside the parcel, but this tool is easy to control so that isn't much of an issue.

I was using a serrated steak knife to break down boxes because it is safer than a box knife and I think easier to use for that purpose. It worked very well and it was fast. Then I started doing research to find something even better. A lot of people like the Kershaw Leek which lists for over $100 and it is definitely not as safe as a steak knife. The I came across the Canary and I have always been impressed with the Japanese when it comes to knives (and many other products) .For $8 it was worth a shot. It exceeded my expectations and I just ordered another one to keep in my kitchen. It is faster and easier than the steak knife and very safe. It is thin and teflon coated so out slides in underneath a box flap and cuts the tape easily, then I plunge cut the tape the length of the box and make a turn when I get to the end without stopping to cut underneath the flap on one side, and because the knife is double sided I can move it back the other way and cut the tape on the other flap with out turning the knife around. This process is so fast and smooth it blows away the steak knife! If the box is really big then I cut the cardboard up in smaller pieces. I was surprised how well the Canary works for this, way better than expected. You can just pull it through the cardboard and it will cut it but it works better if you saw back and forth. Other reviews say it cuts cardboard like butter and that is a bit of an exaggeration but it does an excellent job.
