Adjustable wrenches are nothing new, they’ve been around for a while. You always have to adjust it down or up a bit first though. Sometimes you are off too and then you have to adjust some more. Well now there’s this hydrokinetic wrench that adjusts in a much more convenient way. The wrench has a hidden chamber of water that allows for it to adjust very easily.
To work it, just open the valve, put it on the chosen nut or bolt and then you have to push the gripper on the opposite end. By pushing that it will compress that liquid and adjust the wrench. Once it’s to the desired size, close the valve again so that it stays nice and secure. Then you can loosen or tighten nuts and bolts to your heart’s content. It’s debatable if this is all that much more convenient than a normal adjustable wrench. Still though, using hydrokinetics is a much cooler method. You can purchase it through Think Geek for $24.99.
