CANARY Mini Box Opener Handsaw Safety Cutter Tool - Non-Stick Coated Blade - Safe Package Opener with Serrated Japanese Steel Blade - Made in Japan

Very quick at opening endless cardboard packaging. Quicker than scissors and feels safer. Serrated blade is good for cutting through a bit of cardboard if needed. Short blade means I am not afraid of damaging contents of box.

So useful for opening all sorts of packaging and much safer than scissors. Brilliant product.

Very handy for breaking down cardboard into smaller sections for recycling. Handy for opening packages. Not sure how I made do without it!

After being totally fed up with getting cuts and the awkwardness of using an open scissors or an actual knife to open the literally dozens of Amazon (and other) packages we get each month, I found this - and SO glad I did! We got the pink (shorter, serrated edge, with the non-stick coating). Literally a game-changer for SO many packages and plastic-sealed products we are always opening. The "blade" is serrated, but while it cleanly and easily slices through all plastics and all cardboard boxes (even pretty thick ones) with ease, it does not cut the user, simply because you brush against the cutting edges. Even if you gently rub it across your skin, it's rough, and maybe leaves a white scrape mark, but no cutting whatsoever. Shocking given just how easily it slices though heavy-duty cardboard. Simply a brilliant product! As far as the "protective sheath," it's more of a small, flimsy shaped plastic that slips over the blade, and part of the handle. I wouldn't rely on it for anything, really (it's about the consistency of a thin plastic sandwich bag, not hard plastic). At first, I thought we'd regret not having gotten one with an actual hard protective sheath, but given that the serrated edges do no harm on their own, without applying a decent amount of pressure (but not too much, it's still easy to cut boxes/seals easily), it doesn't really need it for just sitting in a drawer, waiting for it's next use.n Personally, I like this size, because of the leverage it offers - longer blades have greater chance of hitting something you don't intend (like if something delicate is packed towards the cutting edge of the packaging box), but this can only go so far inside, and even so, is unlikely to demage anything but the most delicate (or cardboard/paper-based) item inside the box, even if it did hit it. It's lightweight, is well-balanced in the hand, and easy to grab regardless of whether you're right- or left-handed (it's serrated on both sides). I've found it's much easier to pull towards you (which we always hated using scissors!), rather than pushing away... just seems to have much greater leverage. Really a great product - just ordered a 2nd one to have one upstairs and down.

以前に同シリーズの「ダンちゃん」を使っていて切りやすかったため、こちらのカイちゃんも購入しました。開封作業で使ってみると、刃の入り方がとても自然で、余計な力を入れなくてもスムーズに切れます。 深く入りすぎない感覚があり、パッケージの開封でも扱いやすいです。フッ素加工のおかげか引っかかりも少なく、切り始めから終わりまでストレスがありません。 サイズ感もちょうどよく、日常的な開封作業に向いている一本。ダンちゃんが合っていた人なら、違和感なく使えると思います。

便利だわー穴にストラップつけて首からさげられるし、刃の感じも良い結構切れ味が持ちます

Lost a similar tool that I had for 30 years. This is an excellent replacement even better than what I had before. Hopw it lasts as long.

I’m so happy with this purchase. It’s great for opening packages you get in the mail. Another item it works very well on is, those round adhesives that come on almost any item that is holding a flap together, see photo. I love the pink color, as I can see it well in my drawer. I was worried the tool would be too small for holding in your hand, but it works great. This would be a great stocking stuffer for family members!
