Sharpening stone (abrasive grinding wheel) for slicers, size 43 × 8 × 6 mm (diameter × thickness × centre hole). It is the wear part of the built-in sharpener assembly that restores the edge of the circular blade. For AGW slicers and compatible sharpeners; ideal for finishing the blade edge. Fine grit: it refines the cutting edge and revives its sharpness — use it after the coarse-grit wheel for a clean cut. Replace the stone when it is worn out, glazed or no longer bites. Check the three dimensions (diameter, thickness, hole) on your machine: they determine compatibility regardless of brand.
