The monkey wrench was first invented by Charles Moncke in the year 188 Moncke was an English blacksmith who wanted a better way to hold and turn nuts and bolts. He ended up inventing the monkey wrench, which was designed to hold the nut or bolt in place while it was being tightened.
The tool was extremely useful and quickly spread throughout the world. It is still used today, and its popularity has led to its use as a metaphor to describe an obstacle or a situation in which a solution is not easily found.
