Grinding wheel (emery stone) for slicer blade sharpeners, compatible with FIA Boston models and other compatible sharpeners with the same mounting size.

• Diameter/thickness/hole: 50x12x10

This is the rotating abrasive stone fitted on the slicer's sharpener, used to hone and restore the edge of the blade for a clean, precise cut. Replace it when the original emery wheel is worn, glazed (smooth surface that no longer sharpens) or damaged — typical symptoms are poor sharpening results or a blade that no longer cuts properly. Always check the size (50x12x10, diameter x thickness x hole) before purchase to ensure correct fit with your sharpener.
