What tool classification best describes standard wire strippers?

Standard wire strippers are best classified as a constant-Mechanical Advantage (MA) tool because they utilize a specific set of mechanical principles in their design that allows for a consistent advantage when cutting and stripping wire insulation. These tools are designed to provide a steady force to efficiently strip insulation from electrical wires without damaging the conductor underneath.

The mechanism employed in wire strippers allows a user to apply a simple mechanical action—squeezing the handles—to perform the task, which translates into a greater force exerted on the wire insulation compared to the user's input force. This type of tool does not rely on power sources; instead, it operates through manual effort, exemplifying the characteristics of a constant-MA tool designed to simplify tasks that require precision and control.

In contrast, categories such as dumbbell tools refer to tools used primarily for lifting or carrying, access tools are used to gain entry to confined spaces or areas, and power tools operate using external power sources, none of which accurately describe the function or operation of standard wire strippers. Thus, identifying them as constant-MA tools aligns with their function and the principles of mechanical advantage in tool design.
