After refreshing some razors on a yellow coticule, I am getting a good, close shave but the blade does not glide over my face like it does when sharpened professionally. I am interested in the possibility of adding the Shapton stones in 16k and 30k as finishers. What do you think? I did some research on esher stones and their site indicates they are not compatible with coticule edges. What are your opinions on the Shaptons? Thanks.
