Which tool is primarily used for shaping and detailing haircuts?

The tool that is primarily used for shaping and detailing haircuts is shears. Shears are designed with sharp blades that can cut hair with precision, making them ideal for achieving detailed texturing and subtle shaping around the edges of a haircut. Their sharpness and the length of the blades allow stylists to create clean lines and layers, which are essential techniques in both modern and traditional haircutting.

While razors can also be used for texturizing, they serve a different purpose and create a different effect, often resulting in softer edges. Clippers are typically utilized for bulk hair removal and creating uniform lengths, while combs are essential tools in the hairstylist's arsenal for sectioning hair and guiding the cutting process but do not perform cutting themselves. Thus, shears remain the primary choice for detailed and artistic cutting techniques.
