CANARY Corrugated Cardboard Cutter Handsaw Non-Stick Coating Blade [Dan Chan], Safety Box Cutter Package Opener Tool, Made in Japan, Yellow (DC-190F-1)

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.

This cardboard cutter knife is an exceptional tool, crafted in Japan with meticulous attention to quality and functionality. The cutter features a 2.95” double stainless steel serrated blade with a truly innovative nonstick coating. This coating prevents adhesive tape from sticking to the blade, making package opening a breeze and significantly reducing the hassle and time typically associated with cutting through taped boxes. The blade slices through thick cardboard effortlessly, supporting its claim of ultra-efficiency. The cutter's handle is made from strong polypropylene resin, ensuring durability and a secure grip. Its vibrant fluorine yellow colour makes the tool easy to spot among other tools. The entire construction is robust, with the blade firmly attached to the handle, promising longevity and safety. Speaking of safety, the design of the microfine serrated teeth is commendable. It is sharp enough to cut through materials easily but safe to the touch, reducing the risk of accidental cuts—a vital feature for a tool that can be used at home or in a professional setting. This cardboard cutter knife is practical and aesthetically pleasing, making it a wonderful gift for professionals and DIY enthusiasts. It comes packaged with official English instructions, adding to its appeal and user-friendliness. Conclusion: The CANARY Japanese Corrugated Cardboard Cutter is a superior tool that combines Japanese craftsmanship with practical design. It’s perfect for anyone looking for a reliable and safe utility knife that can handle everything from simple crafts to heavy-duty packaging tasks. A valuable addition to any toolkit!

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.

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.

Was looking for something to cut boxes with as my wife and I do a lot of online shopping, and came across this in my research. I think everyone hyped it up a bit too much, I thought it'd glide through cardboard like butter. It doesn't, but with the right technique, it does a pretty amazing job. The serrated edge just does its magic, cutting the cardboard in relative ease, without relying on sharpness. So I expect it to be low maintenance AND not risk cutting our hands by accident! Now it's actually a fun chore to cut down boxes for recycling! One thing to note is to avoid glue or glue residues from labels and what not, as those can get into the serrated edge and can be annoying to clean off.

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.

Not much more effective at cutting cardboard than the Westcott ceramic blade cutter at less than half the sale price of this Canary cutter. Unless you are impressed by Japanese fairy dust, I don't see any particular reason to pay double and get this cutter.

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.

Parfait pour ouvrir aisément les cartons.

カッターのような危険もなくサクサク気持ち良く切れます！

I use this cardboard cutter all the time. It's specifically designed with serrated blades for cutting through cardboards and that it does very well, much better compared to simple box cutters or other cutting instruments I used in the past. It's nice to hold, light and above all, cuts smoothly and precisely.
