Which tool is essential in a haircut to create precise lines and edges?

  1. Comb

  2. Flat iron

  3. Scissors

  4. Clipper guard

The correct answer is: Comb

In a haircut, a comb is an essential tool to create precise lines and edges. Combs are used to section off hair, hold hair in place while cutting, and guide scissors or clippers for accurate and straight lines. While flat irons are used to straighten hair, they are not specifically designed for creating precise lines in haircuts. Scissors are commonly used for cutting hair, but a comb is typically used in conjunction with scissors to ensure precise cutting. Clipper guards are used with clippers to control the length of the cut, rather than for creating precise lines and edges in haircuts.
