KEY SMARTKeySmart Safe Box Opener - Key-shaped Safe Package Opener For Everyday Carry, with Finger Protection Fits Perfectly on Keychain or Inside a KeySmart - Great Stocking Stuffer (Black)

I stock cards at supermarkets. I don't want a knife or anything I might accidentally leave in a box. This works great. I have it on my keys and can put them in my pocket after I open the box. It does not cut skin, but it does cut the tape or box, sometimes it takes a couple times to go through. It works great for the few boxes I need to open. I don't think I'd like it for a regular stocking job where you need to open multiple boxes. It is a safe alternative to a box cutter.

These package and letter opener keys are great value for the money. I use them frequently and find them to have amazing functionality and utility. The design is amazing and the subdued black color goes perfectly with the solid black theme of the majority of my sets of keys. I highly recommend these to people who receive and open packages regularly as they are definitely a great value for the money!

I like it. It’s pretty good opening things unfortunately for me it’s a little too small so I kind of drop it. Otherwise, it’s a good product.

It cut tape-level things, not sharp, but it spared me damaging my actual keys. That said, it's too fragile and it eventually got chipped and then it was useless. To be fair, I was using it as a flat-head screwdriver - but if I had a pocket knife, it wouldn't have chipped.

Considering this is plastic, it works well. It doesn't cut everything my cheap metal key chain knife would cut, and it is nearly useless as a pry bar even for plastic clips as it is not stiff enough. Haven't taken it through a security checkpoint yet, next time I do that will be entertaining.

Size is deceiving looks as if its a normal key size! Actual size is half the size of a normal key if that!

I love this for my teenaged drivers. It looks like a key that they put on their keychain. No one knows that it is a knife and they have a little extra sense of safety when they are out at night. I recommend this.

You'd figure that a key-shaped thing from a company called KeySmart would make a tool out of a durable material, like a key perhaps, not one that's already showing dents after using it two or three times. I suppose they call it "PA46" to sound fancy and try to play it off. But it's just a thin piece of plastic that weighs basically nothing. The credit card that's already in your wallet is more durable than this. You could cut a scrap out of a bottle of soda and it would probably also be more durable than this. And it wouldn't cost six dollars. There's a reason there's an option to buy this as a 3-pack. The only reason it's two stars instead of one is that it's *technically* fine for the one stated purpose of cutting through basic tape (good luck with reinforced tape, and certainly not actual boxes). But y'know, real keys made of real metal are good at that too. And it'll last for years instead of maybe a couple weeks. A versatile EDC tool this is not.
