Description

Powerful coarse grit for rapid edge renewal

The Red Shrimp #220 coarse whetstone is built for heavy steel removal and fast reshaping. Its silicon carbide abrasive cuts aggressively, making it useful for restoring chipped or blunted blades made from hard carbon or high-speed steels.

Soak briefly before use to activate the surface and achieve consistent slurry formation. Compact and durable, it can also serve as a short-term flattening stone in a pinch, although a dedicated flattening stone is better for regular maintenance.

Begin your sharpening sequence with this coarse grit, then refine using the Naniwa Gouken Deluxe 1000 grit whetstone. Keep your sharpening stones level with the Grooved Flattening Stone or browse the full Japanese tool care and sharpening range.

Tip: Use slow, even strokes and rinse often to clear metal build-up for longer stone life.
