5.0 out of 5 stars Very light - good for a hiking or backpacking kit
Reviewed in the United States on October 12, 2020
Color: 9pcsVerified Purchase
Sure, you could strap on a Rambo knife and carry an 80 pound pack with all your heavy-duty survival gear while grunting and groaning through your short, miserable days backpacking up and down hills on a well-established trail. where your real-world risks are mostly from falling and getting hurt by your own gear. Or you could actually cut that pack down under 20 pounds and smile your way through high-mileage days with energy to spare in camp. One of this won't automatically take all those pounds off of your pack, but ya gotta start somewhere.
Besides handy little utility knives, backpacking was the reason I got these. The primary times I need a knife (and yes, I carry a small sturdy one for slightly more serious tasks) is for cooking. Slicing vacuum seal bags and other packages open and such is a primary use. I didn't want to have to dig up my knife just for this, but having one of these babies in my cook kit is just plain handy, and at 1/3 ounce each, this weighs just over nothing.
They are also handy for opening Amazon packages, though it may be a while before Amazon delivers to my campsite via drone, Hunger Games style. (But that would be kinda cool!)

These mini "box cutters" are extraordinarily convenient. They are safe, easy to use, and very affordable. When you use one you wonder why they weren't invented decades ago. I bought a large pack and leave one in all the places I find myself needing a blade or scissors (kitchen drawer, desk, sewing kit). I also give them to friends as a gift. Many attach them to their key-chains. That's how handy they find them.

I love these things they're so handy. Have one in every room. If you had kids I wouldn't do that but otherwise I found a use form everywhere that I have them. My main use is opening up packages and it's so much easier and faster than trying to use scissors. These are very sharp, and may accidentally cut right through the cardboard when you're just trying to cut the tape lol. So again, use caution if you have kids but I love these, they're fantastic, highly recommend
