Lansky 4-rod Turn Box Crock Stick Sharpener (LCD5D)I had one of these for a while and let my best friend use it to sharpen one of his knives. He was very pleased with the results and impressed with the size and simplicity of the tool. I started to give him my old one and keep the new one. Gave him the new one instead, he was very surprised and carries it with him to show others.
