Tsushima natural stone is a rare and highly prized Japanese whetstone, renowned for its fine quality and ability to produce an incredibly sharp edge on knives. Sourced from the seabed off Tsushima Island, it provides a balanced combination of grinding and polishing, giving knives a consistent and lasting sharpness. The stone is sought after both for its ability to provide a beautiful finish and to ensure a razor-sharp edge, making it popular with both amateurs and professionals.
