What weight pencil is recommended for darkening lines and for lettering? *

While the softer B pencils are generally considered the best for shading, there's no reason to discount the harder H pencils. The HB and H are good choices for fine, light, even shading. However, they too have drawbacks. Pencil grades from HB through H, 2H to 5H get progressively harder and are easier to keep sharp.
