Dedicated pencil sharpener

Specialized sharpeners that work on non-standard-sized pencil-shaped markers, such as crayons used in elementary school, can be used. Sharpeners with two openings are common, one for regular pencils and one for larger crayons. A sharpener with a single blade for crayons can be used, which is sometimes included in the crayon case. These usually come with a plastic scraper, which is good enough for soft wax.
An artist's or draftsman's pencil sharpener keeps the graphite intact and sharpens only the wood (some models can be adjusted from standard to wood-only mode). Then, the graphite lead is honed into a pointer with a sharp point lead whose sharpening is only ahead without wood. Lead indicators are also available for mechanical lead holders with larger diameter leads (eg 2 mm) with removable/refillable leads. Some sharpeners used as long point sharpeners have a second hole where the blade sharpens the untouched graphite to a long, more precise point, which is longer than using a single hole Spot sharpeners can become sharper.
Carpenters can use carpenter pencils, which have a flat shape that keeps them from rolling away while still providing a constant line width. Traditionally, these pencils were sharpened with a handy tool such as a plane or sandpaper. Rotary pencil sharpeners of these tools are now available, where a rotating plastic collar holds the pencil in place, although they then sharpen them to the usually conical point of a round pencil, forgoing some of the uniqueness of a carpenter's pencil aspect.
