It really is amazing how necessity can inspire people to do many mind-boggling things. Just look at the Geekey which is no bigger than your standard sized key. But fully integrated into this nifty key are 16 different tools that will make all other multi-tools pale in comparison. Made of 17-4 stainless steel, the Geekey comes with a bit driver, metric ruler, wire bender, scoring tip, serrated edge, smoking pipe, file, and a bottle opener. There’s even a wire stripper, a protractor, and a closed wrench in both metric and imperial measurements. There are various screw drivers, too. It’s everything you need in a key.
