What cutting technique involves using a straight edge to create a clean, blunt line in a haircut?

The technique that involves using a straight edge to create a clean, blunt line in a haircut is known as blunt cutting. This method is characterized by the use of a straight edge, such as shears or a razor, to achieve a precise and uniform length across the hair. Blunt cutting is often used for creating bob cuts or achieving a straight-across fringe, resulting in a sharp and polished look. The focus in this technique is on maintaining the integrity of the hair's weight and volume at the ends, which emphasizes a strong silhouette.

In contrast, other techniques like point cutting, slicing, and texturizing have different goals and effects. Point cutting typically involves snipping the ends of the hair at an angle to create texture and soften blunt edges. Slicing is used to remove bulk or add movement by sliding the shears through the hair while cutting. Texturizing aims to reduce weight and add dimension to the hair, often resulting in a softer feel rather than a blunt finish. Therefore, blunt cutting is specifically aimed at achieving that precise, clean line that defines the look.
