In many carpentry and locksmith works, it is necessary to mark many lines parallel to one of the sides of the board or board element.. In this case, it is not necessary to draw each line with a ruler and pencil. Just use the stylus and mark the distance of each line from the edge. After that, we set the extension of the stylus arm one after the other. By moving the stylus with the body along the board, we draw parallel lines. There are also styluses, in which the carpentry pencil is attached.
