The Shapton Glass Stone is a must-have for professionals and home cooks serious about knife care. This synthetic stone offers uniform abrasion, requires no soaking, and sharpens faster while wearing down slower than other synthetic stones. Its durable glass backing ensures lasting performance, even when the abrasive surface thins.

Unlike traditional whetstones, Shapton Glass Stones produce no odor, making them ideal for quick touch-ups during service. The HR (High Resistance) series works well with both stain-resistant and carbon steel knives.

How to Use Shapton Glass Stone

Before Use

• No soaking required Unlike traditional whetstones, Shapton stones require little to no soaking before use.
• Splash water onto the surface before sharpening. If the stone feels dry, apply more water as needed.

After Use

• Do not keep soaking after use.
• Store in a dry, well-ventilated area to prevent cracking or warping.

Additional care

• Flatten the stone periodically using a lapping plate or stone fixer to maintain a level surface. Use light, even strokes to avoid unnecessary wear on the stone.
• The Shapton Diamond Stone Fixer should not be used with #220 stone. To flatten it, use another stone of the same grit as a stone fixer.
