Before I get started on my in-depth analysis, let me say that the Ratcheting ReadyWrench by Black & Decker may be the single greatest hand tool I’ve ever used. Here’s the basic information: The Ratcheting ReadyWrench is a double ended closed wrench/ratchet. Each end of the ratchet is capable of pivoting to give you four different sizes per end. Sure, I’ve used dog bone wrenches similar to the Ratcheting ReadyWrench, but none so nice. Oh, by the way, it’s not just four sizes but eight. The Ratcheting ReadyWrench is machined to be able to properly grip both standard size bolts and the nearest equivalent metric. For example, ½” and 13mm can each fit in the same hole. But to make this tool even better, Black & Decker added ratcheting mechanisms to both ends. So instead of removing and resetting the wrench to turn more, all you have to do is crank backwards just like a ratchet.
