A diamond sharpener is a handheld tool that is used to sharpen knives. It consists of a diamond-coated rod that is mounted on a handle. The rod is inserted into the blade of the knife and then moved back and forth in a sawing motion. This action will remove metal from the blade and will eventually create a sharp edge.
Diamond sharpeners are considered to be one of the best ways to sharpen a knife. This is because diamonds are one of the hardest materials on earth and can therefore effectively grind away metal. Additionally, diamond sharpeners create less heat than other methods (such as using a honing steel) which means that they are less likely to damage the blade of your knife.
