Carpenter pencil

Pencil designed for use by carpenters

A carpenter pencil is a pencil that has a body with a rectangular or elliptical cross-section to allow it to be used as a quick reference to 1/4 and 1/2 inch measurements. The shape also helps prevent it from rolling away as a secondary function. Carpenter pencils are easier to grip than standard pencils, because they have a larger surface area. The non-round core allows thick or thin lines to be made by holding the pencil slightly rotated, particularly useful in carpentry where thin lines are required for high precision markings and are easy to erase, but thick markings are needed to mark on rough surfaces. The pencil is robust and strong to endure heavy duty environments like a tool box, construction site, or carpentry shop. The core is typically stronger than in other pencils. As such, carpenter pencils are often used by builders because they can mark on surfaces like concrete or stone. The shape and lead density aid in marking legible lines with a straight edge that are clear and easy to follow with a saw blade. Carpenter pencils are typically manually sharpened with a knife, although special sharpeners can be used.
