Bought many more for stocking stuffers


This works very well. I was tired of everyone using my good sharp knives to open packages. Bought one and liked it so much ordered more for family and other locations in my house.More > < Less


Great boxc-utter


This is my second purchase of this cutter. I bought one for my boyfriend and then demonstrated how well it works. He loved it as much as I do. It cuts cardboard so easy and really makes cutting through the heavy shipping tape on Amazon packages easy. I have the 3”.More > < Less


Best for the job


This little gadget cuts through package tape without snagging either my fingers or the merchandise. We have 3 of them now in various rooms. If you do a lot of online shopping, you need this.More > < Less


Cutting cardboard just became fun


We get lots of deliveries and with a VERY small communal recycling bin for cardboard we are often stuck piling cardboard in our home until there’s room to recycle it. I’m able to cut the cardboard down into much smaller pieces than I normally would which makes everything easier. In fact I’m even able to fit more into the recycling bin!
Listen, this thing makes the job so easy I’ve begun not only looking forward to having to cut cardboard but also cutting out really fun shapes just because I can!!

I’m going to buy more of these for gifts FOR SURE.

Perfect for the job


This does the best job EVER of opening taped boxes. Some companies seem to hire workers whose whole job is taping their boxes, but this little gizmo slices through it all, and it doesn't cut skin if you slip. I just bought 2 more.More > < Less

About Canary

Box Boss

The serrated box cutters from Canary blend utility with Japanese craftsmanship in well-made knives.

The blades set them apart from the typical ones. The fine, sawtooth, stainless steel edge takes down cardboard boxes and packing tape. Because they’re edged on both sides, you can cut upwards or downwards. And the smooth, rounded tip prevents unwanted damage on the goods inside the box.

The blades adjust to get the just-right length to tackle boxes, packing tape, straps, or even to remove labels. The non-stick coating keeps adhesives from gumming the blades up.

Each knife is made in Seki, Gifu, Japan, an area renowned for its long tradition of knife and cutlery craftsmanship. This heritage is apparent—these handy blades make everyday cutting tasks a lot easier.
