Where This Stone Fits in Your Sharpening System
The 8000 grit stone is always the last stone in the progression - never the first. Use it after a coarse or medium stone has already restored the edge. At 8000 grit, the stone removes almost no metal - instead it smooths and polishes the microscopic scratches left by coarser stones, refining the edge to a mirror-like finish that is visibly sharper and longer-lasting. For Japanese knives like Shun, which are sharpened to a fine 16° edge, a high-grit finishing stone makes a noticeable difference to both sharpness and edge retention. The included base and case keep the process clean and stable.
How to Use
Always use after a coarse or medium stone - not as a standalone sharpening stone
Fill the case top with water to the fill line and soak the stone for 5-10 minutes
Place the stone in the ribbed base - fill the base reservoir with water to keep the stone wet
Use light pressure - the 8000 grit stone does its work gently
Sharpen at 16° for Japanese knives, 20° for Western knives
Rinse and dry after use, store in the case flat to prevent warping
