Features: 1. Deep hole design: The carpenter's pencil features a 45mm extension with a needle nose tip, allowing access to hard-to-reach areas such as through-holes or tight spaces where other carpenter pencils cannot reach. 2. Built-in sharpener for precise marking: The sharpener is securely screwed into the top of the mechanical pencil, preventing loss and ensuring the pencil remains sharp for accurate markings. 3. Mechanical pencil with comfortable grip: The pencil is designed to prevent slipping, reducing hand fatigue during repeated use. The pen clip allows for easy attachment to bags or pockets, making it convenient to carry and less likely to be misplaced. Ideal for construction and masonry work. 4. Versatile surface marking: This solid woodworking pencil can mark on various surfaces including metal, plastic, glass, wood, and paper. The lead is durable and provides strong, visible lines. The yellow lead is especially effective on dark surfaces where standard gray lead may not show clearly.
