This wrench falls into the “why didn’t we think of that” category. For all intents and purposes, this is an adjustable wrench that conforms to a variety of nuts and bolts, and evenly distributes force on all of the work surfaces. It also takes the pressure off of the corners of the fastener, which would, in our minds, reduce the chance of stripping.
The only downside we can see is that the large ring housing the moveable lock pins is of substantial size, so the Bionic Wrench is immediately ruled out when working in a limited space area.
For household or general use, the Bionic Wrench looks like a great way to lighten that small toolkit a bit. It is available in 6, 8 and 10-inch sizes, and starts at around $28.95.
