I used this to sharpen my pocket knives and kitchen knives very successfully, some of them fairly busted up at the start. For knives bigger than 4 inches or so though, only the pull-through parts will really work, so you might want a stone. In terms of grit it basically goes carbide pull-through (??? grit)---> diamond rod (400 grit)---> ceramic pull-through and rod (1000). the carbide is really only for very damaged blades so it's good to be able to use the diamond rod, you just need to understand the basics of sharpening. Likewise the ceramic rod is also useful on more than just serrations, especially if your knife doesn't match the pre-set angle of the pull-through. Get the Blademedic and a Fallkniven DC4 (800 grit diamond, 12,000(?) grit ceramic, + the case is designed to be a leather strop), and you have a very simple, portable, and versatile sharpening kit that even a beginner can use.
