A Brief History of Antique Wrenches

Primitive adjustable wrenches, also known as monkey wrenches, are believed to have taken the name from the tool’s inventor, Charles Moncky. He patented an improved version of the wrench in 1858. This fact can help during accurate antique wrench identification.

In use since the early 1800s, these wrenches were commonly made of iron or steel and had a threaded screw mechanism. This system allowed the jaws of the wrench to be adjusted before fitting it to different-sized bolts or nuts.

Antique wooden handle wrenches were popular in the 19th century before the widespread use of metal handles. Often hand-crafted and created by skilled artisans, these wrenches are rare and highly valued by collectors today.

From wooden-handled wrenches in the early 19th century to adjustable models produced during the Victorian era, antique wrenches showcase a wide array of craftsmanship styles and design variations. With the progress of the industrial revolution, mass production of wrenches through machine manufacturing became more common.

Some collectors focus on acquiring wrenches that have elaborate designs, intricate engravings, or were created using unique materials, especially for their handles. These wrenches can range in value from a few dollars for common models to several hundred or even thousands of dollars for rare or highly desired antique wrenches.
