Diamond Willow sticks look fantastic. Great work! Here in Alaska Diamond Willow is readily available, so I work with it quite a lot. CV3's tip with regards to cleaning out the diamonds is spot on. I have found that the flame tip carbide bit to be a great time saver. I also use the ball tip bit as well for the larger diamonds. However, care must be taken when using the coarse bits, as it will readily chew up the wood. Depending on the thickness of the bark, determines if I will use the coarse or fine bit. For the most part you only want to remove a small amount of the bark. I usually just remove the outer surface of the bark, occasionally I will remove it all. Either way you will still get some nice color contrast. One of the common tendencies for those who work with Diamond Willow is to over sand the diamonds....
