Review on Comolife Grindstone Knife Sharpener Japan by Delfin Boone

This product is a complete waste of money... Through trial and error, I found that it does not deliver any sharpening effect on my knives. The product description says it is an industrial and scientific grade sharpener, but it certainly does not perform like one. The only pro is that it looks sleek and modern. However that is not enough to make up for THE fact that the sharpener just doesn't sharpen. Don`t waste your time or money on this useless product..
