Pencil Drawing Sandpaper Block
Use the Sandpaper Sharpening method for your soft-lead drawing pencils .
The sandpaper sharpening method is used by many artists for putting a point on their soft-lead pencils.
Using a standard, hand-held sharpener, is just not well suited for charcoal, carbon, or soft graphite lead pencils; and electric pencil sharpeners can be a little too "aggressive".
Move the pencil from side to side against the paper while turning the pencil between your fingers, sort of sculpting the point.
You'll have to practice to get just the right amount of pressure needed to sharpen the lead without it breaking.
It won't take much to keep the point on the lead after this first sharpening.
Sandpaper sharpening is perfect for those hard-to-sharpen soft lead pencils that tend to break when traditional sharpeners are used.
