Middle Englishplyaction of bending

Historically, pliers consist of metal tools with the ability to grasp and handle small objects, owing their design to the fundamental action of bending. It’s in the 1560s that the term “pliers” began to appear in English texts, emphasizing the tool’s function with its past participle form.

  • Originated: 1560s
  • Usage: Tool for grasping or bending objects

Pliers are unique in English as they are often referred to in the plural form, indicating a singular item made up of two distinct parts, much like scissors or tongs. Their practical design consists of opposable jaws, which are manipulated by the handles – an application of leverage and force.
