I just bought a set of DMT diamond stones and i like them a lot -- i think the DMT system that works like the Lansky would be a great investment. I have always previously used the sandpaper method, which seems to require reprofiling once you commit a knife to the convex edge -- but once the bevel is set it is hair poppin and easy to maintain. I use a section of one of my girlfriend's old yoga mats -- it's bigger than a mousepad and a little softer and thinner - works like a dream. I would say try a few systems until you find one that resonates with you... it seems like everyone has a different preference...
