Constructed with a cutting hook and a small, locking blade edge, it’s capable of slicing through cardboard, paper, rope, straps, and much more. The hook’s unique shape protects the contents of packages from being punctured when opened, and its nonstick Teflon coating ensures the tool won’t get caked up. The other half of the tool features a mini pry bar, bottle opener, and a flathead screwdriver. Plus, at just under an ounce, it goes virtually unnoticed on a keychain or lanyard.
