I use a Lansky Diamond sharpening system with good results. I start with the extra course to establish the edge, once accomplished, I use the finer stones as recommended. I found that the Landsky system even though fairly simple, still requires practice to really get the feel of it. I sharpen all my friends knives and find I get better with this system all the time. Once the desired initial edge is obtained, it will resharpen very quickly from then on. Sometimes it does take a while to get that initial edge, and you just have to plug away until the desired result is obtained.
