These are artificial stones made by the method of binding magnesia.. In terms of hardness, they are slightly harder than Super Stones, and because of the different bonding methods, they are harder and sharpen faster. They are very strong and durable, but this extra hardness means that they are also more likely to crack or chip than Super Stones, so they should be air dried and stored in a cool, dry place. DO NOT soak them or leave them in water when using other stones. During use, simply spray more water on the stone as needed rather than soaking it for long periods of time, otherwise hairline cracks may develop over time. It is recommended to always smooth the stone with a smoothing stone after each use.
