Diamond Sharpening Stone - #360/#600
An economy diamond sharpening stone of #360/#600 granulation with a non-slip base stand for safer sharpening, which prevents the stone from moving around.
Diamond sharpening stones are suitable for the initial sharpening of very blunt or damaged knives. Diamon stones are very abrasive and will quickly remove steel. It can also be to flatten whetstones of higher granulations. The main advantage of diamond stones over whetstones is that they will keep their shape with use. They will remain flat and will not get thinner. However, diamond stones are not as smooth and fine grit as whetstones, so they cannot be used as a final stage for sharpening, or for polishing.
Always splash some water on the diamond stone before sharpening.
