Now even the lowly adjustable wrench needs a battery. Black & Decker may be onto something here, though, creating an 8-inch Automatic Adjustable Wrench that quickly clamps down on any size nut or bolt up to 1.25-inches when you touch its button on top.
This might be a good idea to speed up your wrenching tasks in tight spaces. Just don't get your finger caught in its motorized maw, which can pinch with 220 ft-lbs of torque. Ouch! We still haven't decided if we're lazy enough (or in a big-enough hurry) to drop $27 on this baby.
