Why Is It Called A Monkey Wrench?

edA “monkey wrench” is so named because it was invented by Charles Moncky, a 19th-century British engineer. The design was meant to be an improvement on adjustable spanners that already existed at the time, allowing for the wrench to be quickly and easily adjusted with one hand.

The name has stuck since the first Monkey wrench was patented in 1858, and it has been in use ever since.
