The Utili-Key 6-in-1 Tool is a highly versatile and useful multi-tool masquerading as an ordinary key. Not everyone enjoys carrying around Swiss Army Knives in their pockets or bags. Besides, the TSA won’t let you go anywhere with those cats. The Utili-Key 6-in-1, however, is way more discreet. It’s just a key that attaches itself to any key ring using a self-locking mechanism. If you need them, the tool has everything from micro-flat and Phillips screwdrivers to an eyeglass screwdriver, bottle opener and a semi-serrated knife blade. You can snap it half-open at 90 degrees, or fully extend it all the way. This is a solid stainless steel tool that comes with a lifetime warranty, which means you could well be handing it over to your heirs along with the rest of your wealth.
