New whetstones from the Seki Magoroku series realize perfect sharpening quickly.
Each whetstone is very hard and has a high resistance to wear, therefore there is little transformation in the stone from use. This allows easy and accurate sharpening.
All Seki Magoroku whetstones are made from White Alundum.
