This is tough Australian burl I got from Lee Tannenbaum at http://www.leetreewoodworks.com/index.htm . This specimen has a large number of gum pockets, providing the turner with plenty of opportunity to practice on filling voids and tear-outs. This wood fought back to the point that it took, by far, more time than any pen I've made, however, I love the finished results.
