They are suitable for objects with relatively hard or clear interfaces, such as woodworking scribing, field drawing, etc.; HB pencil refills are moderately hard, suitable for general writing, or playing Contours; Class B pencils, relatively soft refills, suitable for painting, and can also be used to fill some machine-recognizable cards.
