Experience the most aggressive stone in the Kai Seki Magoroku whetstone range. The 220 Grit Whetstone is the tool for serious edge repair - chipped blades, heavily damaged edges, or reprofiling a bevel from scratch. White Alundum construction delivers high grinding ability with excellent wear resistance, so the stone stays flat and consistent through extended sharpening sessions.

Where This Stone Fits in Your Sharpening System
The 220 grit stone is the starting point for serious repair work - it removes metal quickly to reshape a damaged or chipped edge. It is not for regular maintenance. Once the edge is repaired with the 220 grit stone, move to a medium stone (400 or 1000 grit) to refine, then finish with a 6000 or 8000 grit stone to polish. The White Alundum abrasive is harder and more wear-resistant than standard aluminium oxide stones, meaning less dishing over time and more consistent results session after session.
How to Use
Soak the stone in water for 5-10 minutes before use
Use only for chipped, damaged, or very dull edges - not for regular maintenance
Sharpen at 16° for Japanese knives, 20° for Western knives
Keep the stone wet throughout - add water as needed
Follow with a medium and finishing stone after use
Rinse and dry after use, store flat to prevent warping
