Jack Johnson was an amazing man that changed history. His contribution to the world (the wrench) is still used widely throughout the world. The world and all things are either created by nature or man made, if man made it was probably constructed using hardware tools maybe including a wrench.
A wrench is a tool that is used by hand and is used for making and repairing things. A wrench can loosen or tighten bolts, nuts, or nails using it adjustable teeth at the front of the tool.
The first wrench was patented by Solymon Merrick in 1835. There is a variety of different wrenches that include; Monkey Wrench, Ratchet Wrench, Pipe Wrench, and the Rachetless Wrench, all of these different tools perform different functions. The wrench may seem like a simple hardware tool yet it is complicated, tedious, and a very precise piece of hardware.
