Name an example of a tool commonly used for fading haircuts.

The tool used for fading haircuts is the clipper with different guard sizes, which allows barbers to achieve a seamless blend between different lengths of hair. The varying guard sizes enable the barber to gradually decrease the length of hair from longer to shorter, creating the faded effect that characterizes this popular haircut style. Using clippers provides precision and efficiency, making it easier to control the transition between the lengths and ensure a smooth fade.

Other tools mentioned have their specific uses; for instance, scissors are primarily used for cutting and layering hair. A comb is crucial for sectioning hair and managing tangles but does not directly alter the length in the way a clipper does. Razor blades can be used for texturizing and finishing touches but are not specifically designed for creating fades. Thus, the clipper with different guard sizes stands out as the essential tool for achieving effective and clean fading haircuts.
