It's tough to think of anything other than Leatherman when considering a multi-tool — and for good reason, their history of making useful tools contained inside pliers started when they invented the things. The Leatherman Rebar is a nod to that heritage, though it's not without a few modern touches (things like the replaceable 154CM wire cutters). Measuring just four inches in length when closed, it packs pliers, a crimper, multiple knives, a file, a saw, small, large, and phillips screwdrivers, and an awl with a thread loop. Oh, and let's not forget the ruler, bottle opener, can opener, wire stripper, or lanyard ring, nor the stainless steel body and black oxide finish.
Thanks to our smartphones and tablets, gyroscopes have become more and more commonplace. So why not put them to use for more than just rotating our photos and playing games? The Black & Decker Gyro Screwdriver does. Thanks to an internal gyroscope, it automatically senses whether you want to go in forward or reverse, and at what speed, all based on how much you turn your wrist. It can operate at up to 180 rpm and apply up to 35 inches per pound of torque, making it plenty powerful enough for most jobs, and it sports a built-in LED lamp to let you see what you're screwing — which is almost always a good thing.
