I am always a fan of gadgets that solve a solution for multiple devices and save you carrying around bundles of other gadgets. As long as they do the job well, like the classic Swiss Army Knife.
The ingenious Bionic Wrench hopes to solve a number of problems when using adjustable spanners and box-wrenches. It uses six hardened-steel blocks in a circular enclosure that then become the jaws of the wrench and close down onto the six edges of the bolt what the size maybe.
The Bionic Wrench will tighten on the bolt as you push whether screwing or unscrewing, make it easy to fit any sized bolt head and making light work with only one tool rather than an array of spanners and wrenches.
You can see a video of the mechanism in action over at the Loggerhead Tools website.
The Bionic Wrench is available in a range of different sizes from $19.95
