2 Pack Small Pocket Knife, Keychain Box Cutter, Mini Pocket Knife with 0.78 inch Sharp Blade, EDC Utility Knife for Everyday Carry, Safety Box Opener Tool for Office, Cool Gadgets for Men Women

Great for keychains and badge reels, really little which is exactly what I wanted, works well, not sure about replacement blades, which I imagine would be needed eventually

compact size fits easily on my key ring

Has came loose and stabbed me multiple times in pocket.

I have a bad habit of getting things that are adorably small while thinking the items will be sturdy.. 5 bucks a piece is reasonable for this little trinket. And it truly is a trinket. There is no way to change out the blade if it breaks, and it is not very sharp from the get go. But it helps me break down boxes by puncturing the tape...

Good quality.

These knives are very, very small. They're about the size of a USB thumb drive—a small one.The blade is the box-cutting shape, but it isn't a replaceable blade like you might find in a utility knife. The blade is thicker, like a regular pocket knife, and looks like it could be sharpened without too much trouble.The blade locks open and closed. The lock is the press-button you can see in the photos.

My was not great, they both broke at first use.

These are a nice utility tool to have. They are easy to use and seem to be built pretty solid. Easily attached to a key-chain for quick access. Much easier to use than scissors or searching for knife etc. to open packages, which is my primary use. Adjustable blade is great to prevent slicing into package contents.Not sure if the blades can be replaced but I can see a need for that in the future as they wear down.
