When you think of a tool what do you think of? A hammer, a saw, maybe a screwdriver - well I’m pretty sure you don’t think about a wrench. The wrench is one of the most useful and important tools in modern society. Without this single tool we would not be driving cars with combustion engines, and we wouldn’t be using appliances like gas powered stoves. The point is that the wrench might be a little more boring than a hammer or a little less popular than the screwdriver, but when it comes down to it, it has changed the world, and it has paved the path to a future I am sure no one imagined.
