Negative Positive
Title: Removes metal quickly, sharpens poorly
Review: I purchased two of these as potential gifts, and tried one out on a pocket knife that I knew could hold a good edge. The diamond fingers quickly put a decent 20-degree bevel on the blade, but never got it sharp enough to slice paper. The diamond grit is simply too coarse to produce a decent edge; I needed to run it through a pair of crock sticks for a minute or so to get it sharp enough to shave the hair on my forearm. And if you have crock sticks, you don't need the Furi Ozitech...
