Has any one heard of the above hone or has any one have one and how many strokes would i use to refresh a razor. It has one side darker for final polish and one side lighter for a slightly dull razor its basicly a barbers hone i have never used one before i use coti but i'd like to add this hone to my collection. any recomendations on how to use best i have heard you don't need many strokes on vintage barbers hones.
