nano ceramic needs sharpening?

[DavidL41]

Im looking into nano ceramic rc 90 (only used to cut thin materials like leather or vegetable tanned leathers that strops are made from) knives and the description says it will never need to be sharpened. Is that true? If it needs sharpening is the only option a strop or extra fine diamond stones.

Everything will need sharpening eventually.

As far as what you can use , you need diamond / CBN to effectively sharpen ceramic knives. I use diamond films and compounds.
