Curly Koa Twist Pen
Koa is a favorite wood of mine. A Hawaiian wood, it is used fairly often for guitars and ukeleles. The two electric basses that I play both have Curly Koa tops. If you are familiar with the stone Tiger Eye you know what this stuff looks like in person. It seems like you are looking right into the wood. I will definitely be making more items out of Koa, at least when I have gotten enough of Cocobolo, my current addiction.
Sorry, this product is sold. If this was your favorite let me know. I would be happy to make something similar.
