Before I bought it, I watched the video and then tried it out. Maybe it's just me and I'm using it wrong. This thing makes no sense no matter how I use it. According to the packaging, the rough edge is for honing and the hard metal edge is for sharpening. First of all I'm no genius but I don't understand how a shiny slippery surface can sharpen something and it failed. So I tried using a rough edge and it didn't get much better. I went back to the video and it seemed to be using the shiny, slippery side to sharpen. Tried sharpening again, nothing. I can't control it because it slides on the blade. I cannot rate this item as it is probably my defect. I ended up buying another item and attributing it to another money loss.
