A pencil is a pencil is a pencil, right? Not necessarily. Carpenter pencils are rectangular or elliptical in shape, which serves two functions: the prevention of rolling, and grip. Just don’t try to sharpen your carpenter’s pencil in a regular pencil sharpener—it won’t work. You’ll need a carpenter pencil sharpener or a good wood carving knife for proper sharpening. Mechanical carpenter, construction and contractor pencils are all readily available.
