I like to try new stuff and here is something that really makes drawing comfortable. Lynn Miller, Nixa Missouri, makes these sketching pens by hand. He cuts the wood blanks for the pens, drills a hole through the center and glues a brass tube in them. After turning the wood he presses the pen parts together in the wood. His brother George - one of my watercolor students - offered me one of these pens and it took me less than a minute to fall in love with it. Also, the nibs are available in any art material store and come in different hardness grades.
