Ceramic knives sold to the general public are supposed to have a metal core to make them detectable.

All ceramics are available for people (police, military) who need a hard to detect self-defence knife, eg:

People should be terrified that the "undetectables" are reserved only for the "authorities".


Ceramic knives seem quite fragile in the kitchen, I am skeptical they have a lot of potential as weapons, as even small amounts of twisting/shearing force will crack or snap them.
