They're cheap (>$10), effective, and re-newable. These carbide bit sharpeners, which literally shave off metal, are becoming more and more popular cuz they work!
I usta scoff at 'em. I've got mucho high-end kitchen knives and usta sharpen them on a Japanese water stone. Sure, the edge would last forever, but it took "forever" to sharpen a knife that well. Now, I bought a cheapo stamped chef's knife, sharpen it with my Accusharp and off I go. Works great!
The Accusharp carbide sharpening bits can be reversed, when need be. They are also completely replaceable, if necessary.
