Shun 300/1000-Grit Combination Whetstone

Experience the Coarse-End Sharpening Stone for Knives That Need More Than Maintenance

The Shun 300/1000 Grit Combination Whetstone is the tool for repairing chipped or significantly dulled edges - the 300 grit side removes metal quickly to reshape a damaged edge, while the 1000 grit side refines it back to a sharp, working finish ready for the polishing stage.

The Specs

• Grit: 300 (coarse repair) / 1000 (medium sharpening)
• 300 grit: Aggressive metal removal for chipped, damaged, or very dull edges
• 1000 grit: Restores a sharp working edge after coarse grinding
• Compatible with: All double-bevel Japanese knives including the full Shun range
• Origin: Japan

Where This Stone Fits in Your Sharpening System

A complete sharpening system typically runs from coarse to fine - repair, sharpen, then finish and polish. The 300/1000 stone handles the first two stages. Use the 300 grit side when a knife has a chip, a rolled edge, or is so dull that a finer stone would take too long. Move to the 1000 grit side to refine the edge after coarse grinding. Follow up with a 6000 grit finishing stone (such as the Shun 1000/6000 Combination Whetstone) to polish the edge to a razor finish.

How to Use

• Soak the stone in water for 5-10 minutes before use
• Start with the 300 grit side only if the edge is chipped or very dull
• Move to the 1000 grit side to refine the edge after coarse grinding
• Sharpen at 16° for Shun knives
• Keep the stone wet throughout - add water as needed
• Rinse and dry the stone after use, store flat to prevent warping
• Flatten the stone periodically with a leveling stone to maintain a flat surface
• Do not use on serrated or single-bevel knives without specialist knowledge
