During exterior graduation shaping, you should evaluate the:

• A. Type of Tool
• B. Line of Inclination
• C. Parting Pattern
• D. Texturizing Technique

Answer: (B)

Line of inclination is the angle at which you hold and cut the hair as you shape the outer edge, and it directly controls how the exterior perimeter sits and how weight travels from interior to exterior in exterior graduation. Evaluating this angle during exterior graduation ensures the outer edge has the intended slope and the transition around the head is even and balanced. If the line of inclination is too steep, the exterior edge can become heavy and abrupt; if it’s too shallow, the perimeter can look flat or weak. By consistently checking and adjusting the line of inclination, you achieve a smooth, cohesive silhouette that aligns with the interior graduation. Tools, parting patterns, and texturizing affect finish, but the line of inclination is what determines the exterior shape and graduation feel.
