Gerryr,
Nice work. Curly Koa is my absolute favorite figured wood. I have a large stash of left-overs (aka cut-offs) from selling them and I am going to make my next "personal use pen" out of it. I just love it. It is the first figured wood I ever saw in "person". I was in Hawaii on my 10th anniversary and took more pictures of the koa that was used to build everything in my hotel, than I did of the tropical paradise around me. That's when my wife knew I was hooked. Now it is in 3 rooms in my house and in my shop. Oh and did I say, "nice pen"? I never would have guessed that silver would look good with koa. You really captured the great color too.
