I guess that everyone who ever got themselves a lathe ends up making wooden pens. I find it a very relaxing, satisfying hobby. Here are some photos of some pens I have made. I do sell them, but I usually end up giving them away as gifts.
I also offer custom pen orders. If you have a piece of wood that you would like made into a pen I can do so quite reasonably. I have made pens out of little league bats, gun stocks, table legs and redwood limbs for folks that came out quite nice. Contact me via email for further information.
