Nate I used a draw knife, mystic scraper, and pocket knife. I found the draw knife the most useful and as I got more comfortable following the ring I was using it the most of any tool to expose the desired ring. Scraper works great for the finer more detailed work and pocket knife for working the knots. I found lighting to be very important and wore a headlamp while chasing ring and felt it really helped make the rings jump out.
