Mike,
I'm glad you like the pen. And thanks for taking a chance and trusting a new guy. I meant to label the woods but forgot before I sealed the box, they (as you've shown them) are Curly koa, African blackwood with sapwood, Bloodwood (flooring scraps), Gaboon ebony, Paela, and the bottom wood is Spalted maple burl. I hope they work good for some knife handles.
I'm new to PA and bowmaking/archery but have been turning wood, mostly pens, for over 5 years and have made hundreds of pens and plenty of bowls and other things. I'm always willing to trade but any new trades will have to wait until after Christmas, I'm swamped with gifts to make right now. I'm willing and able to trade some pens I already have, make a custom pen, a pen from wood (or other things) you send me or turn custom tools, other items (ex. dogwood/persimmon billets for knapping). I'm glad to be a member of PA and this is a great group of people, thanks for all of the help and info I've gleaned from this site already.
I even found another penturner on this forum, ZanderPommo, who also makes some great pens (he made the osage pen that was posted previously) and has joined a penmaking forum I frequent. It's great to be able to make connections with people who have so many similar interests.
