Why are Mole Grips Called Mole Grips?

Locking pliers, commonly known as “Mole grips,” have gained significant popularity among mechanics and engineers in the United Kingdom. The name “Mole grips” has become synonymous with these versatile and robust hand tools. But why are they called Mole grips? Let’s explore the history and origins of this distinctive name.

The Invention of Locking Pliers

Locking pliers, including Mole grips, were first invented in 1924 by William S. Petersen in De Witt, Nebraska, United States. Petersen patented his innovative design and later trademarked the tool as Vise-Grip, which became the trade name for locking pliers in the United States.

M K Mole and Son

In the United Kingdom, M K Mole and Son, a hand tool manufacturing company, started producing their version of locking pliers in 1955. Under the managing direction of Thomas Coughtrie, the company began manufacturing pliers that closely resembled the Vise-Grip design.

The Birth of “Mole Grips”

Thomas Coughtrie, in addition to producing similar pliers, patented his own version of locking pliers and gave them the name “Mole grips.” The name “Mole” derived from the company name, M K Mole and Son. Coughtrie’s innovation and the distinct name “Mole grips” set these pliers apart in the United Kingdom market.

Popularity and Legacy

The name “Mole grips” gained popularity among professionals in the UK, and the tool became synonymous with locking pliers. The sturdy construction, featuring thick quality metal and a robust round stock bar forming the release lever, contributed to the tool’s reputation for durability and reliability.

Transition and Continuation

In the 1960s, the M K Mole and Son company relocated to Newport, Monmouthshire, where they continued manufacturing Mole grips. However, in the late 1970s or early 1980s, Stanley acquired the Mole company/brand. Despite the change in ownership, the Grip-On brand, manufactured in Spain, continued to use the Mole branding and retained the design features that made Mole grips distinctive, such as the pressed pin and pull-type lever.

In conclusion, Mole grips acquired their name from the M K Mole and Son company, which manufactured locking pliers in the United Kingdom. The innovative design and sturdy construction of these tools, along with their widespread use among professionals, led to the name “Mole grips” becoming synonymous with locking pliers in the UK.
