As far as affordable and portable multitools go, ATOM is easily one of our favorites. While some can get pricey and be bulky to carry around, ATOM (A Tool of Multipurpose) is neither. Pop one on your keychain and you’ll instantly be carrying around all of the following: A bottle opener, a hex bolt wrench set, a ruler set, a flat head screwdriver, a pry bar, a hex bit driver, a protractor, a cross-cut course file and a single-cut line file, along with a ripping tool for good measure. Crafted by a molding injection process using stainless steel, the ATOM is then heat treated to increase strength and toughness. And at fifteen bucks, it’s a lot cheaper than most other options.
