From reading different postings on this forum and watching Lynn's dvd it is my understanding that these yellow belgian coticles cut much finer than a Norton 8K. If I have understood correctly they are considered the equivelant of about 12K. At any rate they get used by members here to put a polished edge on their straights after using the Norton 8K. Hopefully on of the honemeisters will post a reply to verify this and add any needed information.
