Title: Not my best purchase ever
Review: I bought one of these a couple of years ago and I haven't been able to get my knives properly sharp from using it, no matter how long I have spent carefully following the instructions. My partner couldn't believe it wouldn't work and, thinking I might be too easily put off, tried it too, using as many alternative artful variations in technique as he could think of. It didn't work for him either. I ended up throwing it out.Now I use a simple sharpening stone, which is far more effective and environmentally friendly. Better for your arm muscles too.
