Title: Disappointing
Review: I bought this product years ago and found it to work surprisingly well for an inexpensive sharpener. I finally wore out the diamonds and had to replace it. The replacement was identical to the original in every way, except when I used it, it not only didn't sharpen the knives, it made a terrible screeching noise like there's no diamond, only bare metal. I real shame. Time to find another make. I would only give it one star except the original worked so well.
