Edge Master combination Japanese Whetstone with non slip silicon base.
Japanese Whetstones are known for their superior sharpening performance, not only for Japanese tools, but also on their Western equivalents. The loosely bonded abrasive grit is washed out very quickly, as it blunts during the sharpening process; this exposes new, sharp, particles that can get to work on the blade. Water stones are lubricated only with water! Soak the stone for five minutes in water and then you are set to go.
Medium 400 Grit: Good metal removal rate, light scratches. Intermediate stage before finer grits.
Extra Fine 1000 Grit: Slow sharpening rate. Edge is showing a polished looking edge. Very sharp edge better than most factory edges on good knives.
