Anyone ever use a little Obsidian on briar? I don't have a buffer and usually use Paragon but I'm working on a Rhodesian with a lot of crevices and dents that the wax hardens into. I used some Obsidian with a soft cloth and it really brought out the grain...the only downside was a slight tackiness that's steadily going away. Curious of the long-term effects and whether anyone's tried this.
