Idahone Ceramic Stones are used for sharpening knives using Hapstone or Edge Pro knife sharpener. The stone has an extremely high hardness rating.

Idahone Ceramic scarcely wears over time. Ceramic stones are available in three grits: medium, fine and ultra-fine. Ultra-fine ceramic stones utilize the top quality 99.5% alumina and provide a super finish for the cutting edge.

Idahone Ceramic was recently updated to the thickness 6 mm (0.25 inches).

Idahone Ceramic stones should be used with one of these lubricants:

  • WD-40
  • Refined olive oil
  • Oleic aсid
  • Water

Idahone Ceramic stones do not have any minor defects.

Idahone Ceramic stones do not require any preparations. Gritomatic makes additional lapping for Idahone Ultra-Fine and Medium Ceramic stones. This is a big advantage because the difficulty of lapping Ceramic is very high.
