Why have I never seen his before? It’s called the Bionic Wrench, and it’s an adjustable wrench that appears to actually work.
You’ve been there. You need to remove a bolt and you’re either too lazy or too ill-equipped to use the correct-sized box-wrench. Instead, you reach for an adjustable spanner which, if you’ve come this far in my story, you likely picked up for a few bucks at the thrift store. The cheap tool needs constant readjustment and even then it strips the shoulders from the bolt or slips, grazing your knuckles.
Enter the Bionic Wrench, which arrays six hardened-steel blocks in a circular enclosure. When you close the handles, these blocks become the jaws of the wrench and close down onto the six edges of the bolt, clamping it tight on all faces like a box-wrench. And if you orient the thing the right way, it will tighten on the bolt-head as you push, whether screwing or unscrewing.
It’s ingenious. Like I said, this too has been around for a while, but it’s always worth pointing out something so clever and practical.
You won’t be able to toss this in a back pocket like you would a traditional adjustable wrench, nor will it be practical in small spaces, but in the workshop, this looks indispensable. It even works with stripped bolts. Available in various sizes, from $25.
