A card-sized multi-tool for 74 percent off? I'd buy it.

Here's an arsenal that can be tucked away in your wallet. This 10-bit multi-tool allows you to tighten, cut, and inspect wherever you go.

Need to pop open a beer? Bottle opener check. Have an errant hair that needs plucking? Tweezers check. There's also a serrated knife, a big slotted screwdriver, a small slotted screwdriver, a compass, a magnifier, a toothpick, a ruler, and a position wrench. All these tools are only $10 and together are about the size of a credit card.
