knap, I'm with you on the scraper delima. I'm chasing my first ring and am not happy with me tools--draw knife, scissors or an index card size piece of metal I cut from an old hand saw. I'm sure 95% of my problem is lack of experience and not the tools. The draw knife is my favorite, but sometimes it's just to heavy and lacks a delicate tough. The scissors and metal card can chatter too much.
adb, I like the looks of your scraper. Can you PM me info about where to get one?
