Susan...supersearch is not working right now, but I have posted before about Ron Wahl, who had Bryan Bowers and Mike Seeger with their jaws dropping in about 1974.....he claimed to have not broken a string in several years due to his idea of loosening the string and greasing the post with vaseline. So *shrug*....(I play 'mostly' with a fabricated brass pick (sort of like Kilby Snow) which seems to be easier on steel strings...)maybe I'll take some pictures....
