KeySmart Safe Box Cutter - Key-shaped Safe Package Opener For Everyday Carry, with Finger Protection Fits Perfectly on Keychain or Inside a KeySmart (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.

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.

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.

This was a nice little product at first but did not last very long. Dulles down very quickly making it unusable very fast.

Keep it with my mail box key

Very useful easy to use

Does not cut anything more than tissue paper. Small enough to be awkward in your hand... but at least it fits in a key organizer (which is why I got it). I'm glad I tried it but this thing is not up to the task of opening boxes.

I was in the process of upgrading my every day carry and found this.I was first attracted to this due to the design of a Kwikset key which works with my key case. The design makes it concealable. Which makes this easy to carry on a keychain ( or key case) and not look like a knife.It looks sharp but I can place my finger on the “ blade” and not worry about getting cut. The tip is the only real sharp point but as long as you take care- you shouldn’t get hurt unless you’re stupid doing stupid things.The blade cuts through box tape pretty easily. It won’t cut cardboard. I tried it on a styrofoam tray ( something less thick than cardboard) and I wasn’t able to cut it. If anything, I was able to score it. I feel pretty safe using this.
