CANARYCardboard Cutter with Sheath, 7.5" Safe Box Opener/Box Cutter Tool [Non-Stick Coated Blade], Serrated Japanese Stainless Steel Blade, Made in Japan (Bulk Pack of 3)

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!

Cheap price but quality product that works. Cuts through foam core like butter. Heavy duty double corrugated cardboard no match for this tool. I did cut my finger so be careful. I’ll buy another if this one ever dulls or gets misplaced.

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.

These are much faster than box cutters. They cut through both cardboard and tape, and are kid-safe. Highly recommended for anyone with too many Amazon boxes that need to be broken down for recycling!

Love it. Super easy to use.

This really works like a charm. Cuts through boxes and tape no problem. Way safer than a box cuter and works better than the ceramic box cutters I have. Also fairly sturdy with a nice case. I just use it as an opener but it would also work well for arts and crafts projects as advertised.

This is really nice for cutting down large boxes to fit in our recycle. It feels a lot safer than using a utility knife. I really like it!

You wont find anything better for cutting cardboard. Its relatively safe with its special edges, but cuts cardboard like its butter. Slight exaggeration..but its pretty amazing.

通販を利用する事が多く、今まではカッターで開梱していたが、刃先で商品を傷つけないよう、手を切らないよう何となく気をつける意識が必要でしたが、これを使うようになってリラックスして開梱できるようになりました。切れ味がどの程度持つか分かりませんが、買ってよかった商品です。

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。

期待通り簡単に段ボールが切れます。

紛失するまではすぐに段ボールを解体する偉い子になりました最高です紛失してからはまた箱が部屋に貯まっています

段ボールが切れやすく便利すぎます！子どもでも簡単に危なくなく切れます。
