I've enjoyed the Spyderco Sharpmaker. Prior to to that used diamond hones for rough work, a soft then a hard Washita stone, then strop with rouge. I've made knives for 30 years,and build the initial edge on several increasingly fine 2x72 belts, then a buffer. The Sharpmaker is the first "system" that I've thought could do better than I could by hand. Not to say that the other "systems" (Lansky, Wicked Edge, etc) aren't just as good.
