Dr_Ken's Journal: Ceramic Knives - The Paranoia Goes Both Ways

In doing some research on the subject of ceramic knife blades versus steel blades I discovered that most manufacturers add powdered metal to the ceramic mix solely for the purpose of making ceramic blades able to be discovered by metal detecting security devices most commonly found at airports and government buildings. Hmm.... go figure.

The principal ceramic blade ingredient is zirconium oxide which isn't detected by most of these devices. It makes me wonder if these knife makers are doing this are just being civic minded or are quaking with fear at the thought of being subject to lawsuits and/or being fearful of having their products being made illegal.
