The Shapton #320 is a coarse whetstone designed for heavy sharpening work. It removes material quickly and efficiently, making it suitable for repairing chipped edges, correcting bevels, and reprofiling blades. This grit level is also commonly used for thinning Japanese knives, where controlled metal removal is essential for maintaining long‑term cutting performance.
Because of its fast cutting speed, the #320 is often the first step in a sharpening progression. After completing repairs or thinning, users typically move to medium‑grit stones such as Shapton 1000 or Shapton 1500 to refine the edge before finishing on higher grits. This creates a smooth, predictable workflow that works well for both home cooks and professionals.
Its size provides a comfortable working surface, and the stone’s structure allows it to maintain consistent performance throughout longer sessions. For anyone building a sharpening setup for Japanese knives, the #320 is a practical and reliable coarse stone that handles demanding tasks with ease.

Why is the blade length different from the displayed size? The size in the product title is a nominal reference used by knife makers. The actual blade can be slightly longer or shorter due to handcrafting and traditional sizing. Each product page lists the exact measured length.
