Over 40 years later this pencil is one of the most used tools in my art toolbox. I have a nifty sharpener that quickly gives the graphite rod a fine sharp point. An extra bonus is the graphite dust left behind without any wood shavings. I have used the dust as a shading medium. Many years ago I used the dust as a painting medium mixed with rubber cement thinner. I was given the idea by one of my college instructors Richard Bird. When brushed on paper the rubber cement thinner evaporates quickly leaving the dry graphite dust which needs to be fixed to the surface with some kind of fixative. You end up with a wash and water color effect.
