Smith's 6" DualGrit Double-Sided Diamond Sharpening Stone delivers top-tier sharpening performance with advanced technology.

The stone is set in a sturdy plastic base with a protective lid that doubles as a safety feature; simply insert the lid into the base during use to raise the stone's height, allowing your fingers to grip lower for added safety and minimizing the risk of accidental cuts while sharpening.
