Where This Stone Fits in Your Sharpening System
The 400 grit stone is the starting point for most sharpening sessions where the edge needs more than honing can provide - small chips, shape correction, or rust removal. Once the edge is restored, move to a medium stone (1000 grit) to refine, then finish with a 6000 or 8000 grit stone to polish to a razor edge. The included base and case make this the most practical entry point into whetstone sharpening - the soaking tray, non-slip base, and water reservoir mean everything you need is in one compact kit.
How to Use
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
Sharpen at 16° for Japanese knives, 20° for Western knives
Keep the stone wet throughout - add water as needed
Follow with a 1000 grit and finishing stone after use
Rinse and dry after use, store in the case flat to prevent warping
