What do barbers use to create a clean neckline during haircuts?

The creation of a clean neckline during haircuts is typically best achieved with clippers or straight razors. Clippers are designed to quickly and effectively remove hair while allowing for precision and control, making them ideal for shaping the neckline. They can create a sharp and defined line, which is often desired in many haircut styles.

Straight razors, on the other hand, provide an exceptionally close shave that results in a very clean look. Barbers often use straight razors to refine the neckline after using clippers, ensuring that the finish is neat and professional.

The other tools mentioned, while they serve important roles in grooming and haircutting, are not primarily intended for creating a clean neckline. Scissors or blades can be used for cutting, but they don't provide the same level of precision for neckline detailing. Combs or brushes are mainly used for managing hair and do not directly cut hair. Electric shavers or trimmers might be used for touch-ups, but they do not offer the same level of control and sharpness as clippers and straight razors when defining a neckline.
