Just FYI:
Absolute hardest material for knife blades is ZrO2 (Zirconium dioxide == Ceramic).
It also the most brittle, but never rusts and holds sharpness for insane amount of time.
- somberi 8y agoKycoera is one popular brand. But off late it seems like ceramic knives have hit upon some production efficiency, and there are many brands to choose from. They do blunt, say after 6 months of use. Kyocera for one, provides a free sharpening service if you mail their knives in. Ceramic blade gets sharpened on diamond wheels, and they have to be mailed in.
- gesman 8y agoI own Kyocera kitchen knife as well as some made-in-china ceramic folder. Both are performing really well. If I'd buy Chinese made steel knife - it probably would get dull after cutting 3 sandwiches or so. Ceramic knife apparently performing extremely well and remains sharp as expected. Also - i saw there are ceramic knife sharpeners available - so i plan to get one sometime.
