Fellow Daynoter John Dominik has started up a side business of making pens out of various kinds of wood. From the pictures, they look beautiful. I've asked him to make a rollerball in burl. When the particulars are worked out and he sends me one I'll try to post a picture of it here. But knowing John, I'm sure it will be beautiful and worth the price (he has introductory pricing so put your orders in soon!).
