The creators of the bionic wrench took something as simple as the average wrench and mutated it into 14 wrenches in one. The design is such that it is as easy to use as a pair of pliers. It grabs each bolt/nut on all six flat sides which takes away the stress on the corners. And in addition to that the wrench’s grip of the bolt is superior to the average wrench so it doesn’t slip off and damage the bolt, which usually happens.
The way the 6-inch Bionic Wrench is designed it multiplies the strength of your grip, so you can easily tighten or loosen bolts. And not only can you use it easily, but you can use it super quickly too. You can create speed as well by fully turning the 6-Inch Bionic Wrench, release the grip while still on the bolt, reposition wrench, tighten grip-repeat until finished. There are 14 sizes available from 1/4-9/16-Inch and from 7mm-14mm. It weighs a little under 13 oz making it easy to carry and use.
The Bionic Wrench is the winner of several awards including the 2005 Popular Mechanics Editor's Choice Award, Chicago Athenaeum design award, International Forum Design Award, and red dot international design award. It is made in the USA and has a lifetime warranty.
The Bionic Wrench is available for approximately $25 USD depending on which website you use.
