CANARY Cardboard Cutter with Sheath 7.5" Safety Box Cutter, Box Opener Package Opener Tool for Cutting, Opening, Breaking Down, Crafting, Non-Stick Coating Blade, Yellow, Made in JAPAN

I tried it on my skin and was very impressed that it wasn't sharp on my skin but cut through cardboard like it was nothing!

よく切れる。手は切れない。

Amazon should include one of these free with every Prime membership lol. So useful not just for opening boxes but for breaking them down too! Cuts through cardboard so easily, and much safer than a box cutter. Got the multipack because when friends see them they all want one. Also keep one by front door, in garage, in kitchen, in office. Invaluable if you want to make box forts or create a cardboard robot!

ダンボール梱包のテープを切断するのに最適。ハサミの片方の刃を使うより簡単に切れる。透明のテープでも、ガムテープでも、気軽に切れるので梱包の開封にストレスがなく開けられる。ペーパーナイフではないので、封筒などの開封には向かない。

These are great for opening letters, boxes, packages. Great quality knife, so easy to use. Edges are sharp but not enough to pierce if you press your fingers onto it a bit. Seriously makes cutting through boxes like butter sometimes. I actually like to gift this to friends as a housewarming gift. I’d recommend to anyone in the modern age who likes to buy stuff.
