I think Santa is right on this one. Chrome plating is often too thin to sand down and still last well.

The good news Alan, this might be a sign of good taste on your part. Unfortunately, most Scottish belt buckles sold on this side of the pond are quite shinny. But as others have pointed out, pewter, brushed, antiqued or even brass are available if one looks a little harder. As for me, the next time I see a brass buckle that I like, it is mine.
