Sharpening stone (abrasive grinding wheel) for meat slicers, size 50 × 8 × 8 mm (diameter × thickness × centre bore). Wear part for the built-in sharpener assembly that restores the edge of the circular blade. Compatible with Ironweed slicers and any model using this size. The coarse grit removes more metal and re-establishes the cutting-edge profile on worn or nicked blades: it is the first stone in the sharpening cycle, followed by the fine grit. The stones work as a pair in the sharpener assembly: keep both grits on hand and replace a stone once it is worn out or glazed. Check the three dimensions (diameter, thickness, bore) on your machine before purchasing: they determine compatibility regardless of brand.
