I have a Vintage Russian Shell Strop that I use after honing a razor and was wondering if lather would work on it as it is pretty slick and has a relatively hard surface. I cleaned it with saddle soap and conditioned it with mineral oil when I first got it. It seems to work pretty well now but I think some more cleaning and conditioning would help. Any one tried lathering a Russian Shell or should it be treated like regular leather? Any help or suggestions would be greatly appreciated. Thanks guys!
