Shun 400/1000 Grit Combination Whetstone

Restore. Refine. Ready.

Experience the mid-range sharpening stone that bridges the gap between coarse repair and fine finishing. The Shun 400/1000 Grit Combination Whetstone is the right choice when a knife is noticeably dull but not chipped - the 400 grit side removes material quickly to restore the edge, while the 1000 grit side smooths and refines it to a sharp working finish. Includes a rubber tray for stability during sharpening.

Where This Stone Fits in Your Sharpening System

A complete sharpening system runs from coarse to fine. The 400/1000 stone sits in the middle - coarser than a pure finishing stone, finer than the 300 grit repair stone. Use the 400 grit side when a knife is noticeably dull but undamaged, then refine with the 1000 grit side. For a polished razor finish, follow up with a 6000 grit stone such as the Shun 1000/6000 Combination Whetstone. The included rubber tray keeps the stone stable on the bench throughout the sharpening process.

How to Use

• Soak the stone in water for 5-10 minutes before use
• Place in the rubber tray for stability
• Start with the 400 grit side for a dull edge - sharpen at 16° for Shun knives
• Move to the 1000 grit side to refine the edge
• Keep the stone wet throughout - use water only, no oil
• 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
