I have an edge pro and loved it when I got it. It really allows you to have complete control of your sharpening angles and degree of polish, without all of the practice of free hand sharpening. That being said, I dont really use it much any more. I prefer a japenese combo water stone (800/4000) that I got at Rockler for about 25 bucks. One of the best peices of the edge pro is the fine ceramic rod that it comes with. With that rod you can bring a a correctly sharpened knife back to shaving sharp about a dozen or more times before you have to use the edge pro again. I use that on every knife I make, carry or use in the kitchen.
