Abstract
A marking device for writing or drawing on a given surface can be made of any material that leaves a residue or makes legible marks on a surface. The marking device can be used to make precise lines or shapes on any material, including rough surfaces, such as, wood, concrete, drywall, tiles, etc. The marking device can consistently produce thin lines without needing any sharpening. The marking device can be attached to a support frame, which can serve as a handle for grasping and using the marking device. The support frame can further provide a housing to shield the marking device from damage when not in use. The marking device can be shaped as a razorblade and be configured to fit into any standard utility knife, which may serve as the support frame. Such an arrangement allows a utility knife to be reversibly converted into a carpenter pencil.
