Which tool is primarily used for achieving a straight cut?

The primary tool used for achieving a straight cut is scissors. Scissors are designed with two blades that meet at a pivot point, allowing for precise control in cutting hair evenly. This makes them particularly effective for creating straight lines and sharp edges, which is essential in many hairstyles whether for blunt cuts or layering.

Scissors come in various sizes and designs, enabling stylists to cut hair in a way that suits the specific needs of the client. The even blades help ensure that the hair is cut uniformly, which is crucial for maintaining the integrity of the style.

While thinning shears, razors, and combs serve their own unique purposes in hairstyling, they do not primarily function to create straight cuts. Thinning shears are used for removing bulk and softening lines; razors are typically employed for texturizing or creating softer, more blended finishes; and combs are tools for sectioning and holding hair in place, rather than cutting.
