A crescent wrench has a similar appearance to a monkey wrench, and most adjustable wrenches have a similar look. It is made of steel and has a flat handle that is a few inches long. At the end of the handle, there are two jaws, one of which is fixed, and the other moves when you turn the worm gear or slide adjuster located below it. The jaws are nearly parallel to the handle, unlike a monkey wrench where the jaws are perpendicular to the handle. Crescent wrenches are useful for turning nuts and bolts within a specific size range.

However, the name “crescent wrench” is misleading as it is a brand name that dates back to the early 1900s. People began calling all adjustable wrenches crescent wrenches due to their popularity. Karl Peterson, an inventor from Jamestown, New York, created the original Crescent wrench after being told about an adjustable wrench by a Swedish visitor. Peterson developed a wooden version before creating a metal version, and by 1910, he was already advertising a commercial model. Later, Crescent Tool Company was purchased by Cooper Industries.

The earlier versions of Crescent wrenches look similar to today’s models, but there was also a double-ended Crescent wrench that is no longer made. This type of Crescent wrench had jaws at both ends, one big and one small. The other significant change to Crescent wrenches is that they once had a worm gear, which was like a little barrel that you turned to adjust the wrench. Nowadays, many Crescent wrenches come with a slide gear that lets you adjust the size of the wrench’s opening by moving a slider up and down.
