I have a work sharp guided sharpening system that my wife got me for Christmas. While it is nice it is a little redundant for me since I make knives and have a shop full of belts that I sharpen with. This has the extra stones and strop sold separately. $50 shipped conus.
Here is a you tube video on how they work.
