4 PCS Mini Box Cutter Small Safety Retractable Utility Knife Blade Right Or Left Handed Finger Friendly Package Box Opener with Keychain Hole

These are great! They’re small and compact, which is exactly why I love these so much. Where I work we deal with a lot of packages that will have smaller packages inside that require a box cutter. Having this on my keys makes things so much easier and they are surprisingly sharp so be careful.Pros: Price is the first and the fact you get several for your order. Attach to key ring and simply use. The size is small and fits easily into your pocket. The button on the side supplies good grip when using to uncover the blade.Cons: Durability could be improved. The clips that hold it together can become fringed but you can simply pop them back in. But dropping them or to much pressure can cause them to pop open.

Super convenient for opening packages, a must-have, safety retraction, great bargain for the price!

Buy the 4-pack so you can leave them in strategic locations around the house or office. They work well, easy and intuitive to use. Safer than regular box knives it would seem.

A good little knife with a metal blade but would have liked a locking blade like my old one. Would buy this again for young children in the home though for safety.

Like many of us, there are a lot of packages delivered to the house. I used to flip open a pair of scissors or grab a knife, but these are tiny enough to fit in the drawer, next to the entry way, or on a keychain. I didn't think anyone in my house would use them besides me, so I was disappointed I couldn't find a cost effective 1 pack, but it turns out, we all use them. So all those locations? They have a box cutter now.I wouldn't describe them as locking, they spring closed and you have to press the tab to push the blade out. as a righty, they are oriented well for me, but a lefty might be annoyed having it on the left side since the blade is directionally oriented.

What I like about these box cutters is you can reverse the blade so if you're left-handed you just flip it over and it's much easier to use.

Works great but be careful seems like it’ll break easily during heavy duty use

I had an older one a little bit larger, and I created on my keychain, but it finally broke. This one has a comfortable intention to it, making it easy to bring the plate out and in. People complain. The keychain comes loose. it might. But I throw the keychain away. and use the type of key ring that it cannot slip out of. You have to use a screwdriver to widen it enough to get the blade on, but it's worth it. I carried on my keychain and, when I'm in a restaurant and have to use a packet of ketchup or mustard, etc., I use the right to open it because, half the time they're so difficult open. If I happen to get a package and want to let it open, it's handy. Nothing wrong with this product at all. It's easy to use.
