Most key chains aren’t even worth carrying unless they can serve an additional purpose at some point. The weird-looking DoohicKey might not even look like a key accessory, but trust us, it has the potential of quickly becoming one of your daily go-to tools. Not only does it have a bottle opener, which is always handy to have around, it also features a box cutter edge, a flat-head screwdriver, a three-size wrench, ruler, and carabiner clip to secure to your pant loop or bag. The DoohicKey is made of solid stainless steel, so it’ll be able to take more than its share of abuse. This baby is available in the natural stainless finish or a cool-looking black option, and with a price tag under $5, you’d be silly to pass this one up.
