I wish I could tell you. I bought the naniwa's as they are recommended by Lynn Abrams and Gssixgun as a very smooth finisher. I dont have much experience with honing razors but have been sharpening my edc and kitchen/butchering knives on waterstones for 10+ years. Im buying a few cheap vintages to practice on before trying it out on this razor. I will post my results in a few weeks.
