When going out to collect parcels and lacking tools, it's super convenient to carry a mini box cutter in your bag

It's about the size of your palm. Clip it to your keychain or drop it in your bag's little pocket—you barely feel it's there.

When a package shows up, no more hunting for scissors or jabbing at tape with your keys until the box looks like a raccoon got to it. Just pull this out, give it one quick swipe, and the tape splits clean. The blade's short enough that it won't slice through whatever's inside—no accidental gashes on your new hoodie.

Blade gets dull? Pop in a new one for a couple bucks. Way cheaper than those fancy gimmicky openers.

That's it. No LEDs, no Bluetooth, no app. Doesn't need charging. Toss it in your pocket and go. Lose it? Who cares—it cost less than lunch.
