I like the Edge Pro better than any other sharpening system I have ever used. I like it because it will put whatever degree edge you want on a blade or you can simply use the existing edge on the blade. It if fast and you can put a working edge on a blade or you can put a mirror edge, you can sharpen any blade as sharp as you want it. It just works great!
I sharpen knives on the side and this unit does the job....I get lots of knives that are so dull that won't cut butter, with the Edge Pro it works on them too, just takes a little longer. With ceramic sticks or stones it can take a while to properly sharpen a very dull knife.
I don't work for Edge Pro or have even met the designer, however, I just think it is great and being a sharpening fanatic I think it is the best out there IMHO!
