Final answer:
For a blunt cut, zero degrees of elevation is used to create a clean, even line with a heavy and precise edge, as opposed to higher degrees that create layers.
Step-by-step explanation:
For a blunt cut, you would use zero degrees of elevation. This means that the hair is combed down to its natural fall and cut at a 0° angle parallel to the floor. The goal of this technique is to create a clean, even line with no layering, which gives a heavy and precise edge to the haircut. Higher degrees of elevation are used to create layers and texture, but for a classic blunt cut, no elevation is used to maintain uniform length throughout the cut.
