I've been given a silver Sgian Dhu with a silver badge on it. Lucky me. The badge is silver but the finish is a tad rough and I want it to shine. I've been going at it with silver polish and a yellow duster and after 4 hours I've managed to get the edges starting to look shiny but I've got a life and don't neccessarily want to spend the next 6 weeks rubbing my knife. Any one any tips for getting a good finish on it without wearing it (and my fingers) away.
