What is the purpose of a clippers’ taper lever?

The taper lever on clippers serves a specific purpose of adjusting the length of the cut. This feature allows barbers and stylists to achieve a smoother transition between different lengths while cutting hair. By moving the taper lever, users can easily modify the blade's position, which alters how much hair is cut at once. This adjustment is particularly useful for blending and creating textured styles, enabling more precise control during the haircutting process.

While other options may pertain to functions or tools commonly associated with hair cutting, they do not describe the functionality of the taper lever itself. For instance, a clipper is not designed to adjust its speed with the taper lever, nor is the lever intended for cleaning the blade or styling hair directly. The primary and most relevant function of the taper lever is indeed to allow for incremental adjustments in cutting length.
