Match pencil grade to task from technical drawing to shading and sketching.
Pencil grades range from hard H leads for precise, light lines to soft B leads for rich shading and expressive marks. For note taking and general writing, HB or 2B offers a balance of darkness and durability. Technical drawing benefits from H grades for crisp lines that resist smudging, while artists often prefer 4B to 8B for deep tonal ranges. Consider the paper tooth and intended reproduction method; softer leads may smudge in scans unless fixed. Keep a small range of grades to cover most tasks and sharpen appropriately for the desired line quality.
