Correct routing

Most work in wood or metal requires tracing of dimensions or shapes. Regardless of whether we do it with a carpenter's pencil, with a stylus or even the blade of a sharp tool, it is necessary to guide these scribing tools correctly. Well, we lead the blade or the graphite of the pencil along the angle or wooden strip, so that it fits tightly to the side edge. By leading them away, we can draw a wavy line.
