I have three two small and one large, use them daily


Works great


Just what I needed. I’ve been told that I’m an accident waiting to happen. Although this is sharp the way it is made it’s protected well enough that I haven’t accidentally cut off a finger or a hand (LOL). It’s easy to use, takes a minute to get use to because it is different than all the others.More > < Less


Very handy tool


I enjoy the variety and the creativity of your items. I also want good quality and you provide it.




Serrated blade is terrific - I cut up a lot of boxes and these are the best.


Great new tool


This far exceeds any other box cutter and package opener I have seen or used.

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.
