Pipe wrenches are an essential tool for anyone who works with plumbing or pipefitting. There are many different types and sizes of pipe wrenches, but the two most common are the stillson wrench and the monkey wrench.

The stillson wrench is the most popular type of pipe wrench. It is named after its inventor, Daniel C. Stillson, who patented it in 1869. The stillson wrench has a jaws that open and close like a pair of pliers. The jaws are adjustable, so you can adjust the size of the opening to fit the pipe you’re working on.

The monkey wrench is a type of pipe wrench that was invented in 1858 by Blacksmith Charles Moncky. It has a jaws that open and close like a pair of pliers, but the jaws are not adjustable. The monkey wrench is smaller and lighter than the stillson wrench, so it’s easier to carry around.

So, which is the best pipe wrench? That depends on what you’re going to use it for. If you’re working on small pipes, the monkey wrench is probably the better choice. If you’re working on large pipes, the stillson wrench is the better choice.
