The emery stone is the abrasive disc mounted on the slicer's sharpener, which trims and sharpens the blade's edge.

How to choose the right part: every emery stone is identified by three measurements — diameter x thickness x centre hole (for example 45x8x10, 48x10x13) — all three are needed, because even with the same diameter, thickness and hole can vary by sharpener model.

Grit: coarse for the main sharpening pass (removes more material), medium and fine for finishing the edge — many sharpeners fit two emery stones, one for coarse grinding and one for finishing.

Compatibility by brand: available for Fac, Fia Boston, Berkel, Kolossal, Noaw and General Machines.

If your emery stone has a different diameter, see Diameter 50-65mm or Diameter 40-44mm; for the complete sharpener see Sharpeners.

Frequently asked questions

How do I measure the emery stone I'm replacing?
Measure diameter, thickness and centre hole with a caliper: all three measurements must match the original.

What's the difference between coarse and fine grit?
Coarse grit removes more material to restore the edge, fine/medium grit finishes the cut: many sharpeners use both in sequence.
