Ceramic Knives | knifeopedia

Ceramic knives hold a steady, niche spot in the kitchen knife market. With an impressive hardness rating of around HRC 75, they offer excellent edge retention, but also come with extreme brittleness. To reduce the risk of chipping, ceramic knives are typically sharpened at wider edge angles.

This results in a sharpness that, while decent, doesn’t quite match the precision of a well-sharpened steel knife. Additionally, ceramic knives aren't completely wear-resistant. Over time, micro-chipping along the edge is common, creating a micro-serrated edge that can still feel sharp to casual users—and this perceived sharpness can last for quite a long time.

Ceramic knives are ideal for casual users seeking a lightweight, maintenance-free option that delivers acceptable cutting performance without needing frequent sharpening.

However, they do require careful handling. To prevent chipping or breaking, avoid cutting hard objects, bending the blade, or dropping the knife.
