I love my Ken Onion Work Sharp. There is a bit of a learning curve to it, like all tools, but once you understand what you are doing it works great. I go through probably more belts than the average user since I make knives as a hobby, but I feel that the belts last plenty long for what I am doing with them. I have sharpened swords, machetes, and tomahawks along with regular knives with no problems. I think the question is how much are you willing to spend on a sharpening tool along with how much patience you have for other sharpening methods. This is a more expensive way to sharpen knives, but it will save you a lot of time and takes most of the guess work out of bevel angle.
