CANARY Box Cutter Auto Retractable Blade, Safety Box Opener Tool [Non-Stick Fluorine Coating Blade], Made in JAPAN, Green (DC-20F-1)

Had a ton of furniture boxes to cut up. These box cutters work great! These are safer than the razor blade cutters and actually saw through cardboard boxes like butter. The adjustable blade is nice, but I found that I sometimes accidently released the lock while cutting and the blade would slip down. However, I don't think it was a big enough deal to detract from the amount of time I saved cutting up all the boxes. Must have this in your utility drawer!

This is a great box cutter. Better than anything else ive used. Its easy to use and small enough to fit in your pocket. I can definitely recommend it!

This review for CANARY retractable box cutter with adjustable long blade. I bought this January 26, 2017 and have been using this almost daily and it's so far held up well but that's only if you are cautious not to lose the orange slider piece and that part is the weak point of this item. Pros: The serrated blade cuts really well, and takes a few extra cuts to go through extra tough/thick cardboard. It's also easily operated with one hand. Con: The orange slider has a locking mechanism and when blade is retracted the orange piece at the very end of the internal groove. There's no mechanism to secure it so if you slide it one step further it'll fall out. The orange piece has two parts as the smaller piece will lock the blade. I recently dropped the locking piece and it broke. I wish the design was more secure in that respect. There is another version of this with a round wheel knob for locking I will now resort to using thought the wheel knob makes the blade less compact where the above reviewed version could be slide in your side pocket with no protrusions. This is a great cardboard knife otherwise and highly recommend. Would like to see a version where the blade would auto lock once you push it out and retract when you press a button kind of like the tape measure used by carpenters.

I love having this thing in my pocket. I've never been one of those "EDC" knife guys, but this is so lightweight and useful I carry it around the house. The cutting action is smooth as butter on cardboard and tape, better than my old milwaukee fastback razor blade. Safer too. I'm less worried about my kids finding this and playing with it. I've bought several canary cutter knives and this is my favorite. The longer blades aren't really needed and the retractable makes it more useful to throw in a pocket. There's another set of "auto retracting" blade that I didn't care for, it took too much pressure to keep the blade out if i'm breaking down a bunch of boxes. The only complaint is that I wish they made a model with a clip. I would absolutely adore a fastback style canary cutter with a wire style belt/pocket clip. But this, you won't regret it.

Not that great for cutting cardboard. It doesn't lock into place so it moves around a lot. They are safe to use. No chance of cutting yourself.

Super great. I think we use these everyday for something around the house. Great blade

Faster and lets you make far more controlled and accurate cuts than a generic boxcutter

This tool does what it is supposed to do. It’s weird, but, I kinda love it. Good on the engineers who made this and the manufacturers who made it. Great combination sticker peeler, tape opener and box cutter. All without any real blades.

This is one of those things that isn't just an incremental evolution - it's a game changer. Basically dull(ish) and effectively processes packing tape and cuts cardboard with ease.

They are small so suitable for young kids. small hands are fine. Sharp but they have sturdy grip.

先端が安全設計になっていて、うっかり指先を切る心配がほぼない 横はノコ状になっていて、段ボールを止めるテープも切りやすく、長さも短いので、取り扱いやすい 名前のとおり物流の現場での活躍間違い無し

商品を傷つけることなく簡単に段ボールを開封できるので安心。コンパクトで胸ポケットに差しておけるし、刃ではないので安全。べったりテープが付いてても、綺麗に開封できます。ただストッパーがすぐに解除されるので、常にストッパーごと指で押さえて使用するのが面倒ですので星4です

仕事で段ボールをよく開けるので購入しましたが 安全のためのロック機能があるのが逆に刃をしまう時に 微妙に面倒くさいです。切れも思ったよりいまひとつでした。 小さいお子さんがいて自宅に着く通販の箱を開けるくらいが ちょうどいいのかもしれません。
