Lansky is the only thing I have used on my RSK and I'm certainly no expert knife shapener. I use the 30 degree angle with the fine and super fine stones and have had great success so far. I haven't been able to get it as even as the factor edge it came with but I can get pretty close. It gets it shaving sharp in about an hour and that's good enough for me. <img src="/images/graemlins/smile.gif" alt="" />
