Hide The Kitchen Knives
Knives are one of the oldest tools ever to have been used. In fact, we weren't even technically human at the time. It was Homo habilis that first began making knives from bone, wood and probably other perishable materials that have not survived. The oldest knives that are still around were created from flint. These were sharpened by being repeatedly thrust against a rock or similarly hard surface. Eventually stone, bone and wooden knives were replaced by harder materials such as copper, then bronze, iron, and eventually steel. Modern knives may even utilize more complex materials such as titanium, ceramic, and carbon fiber (although steel is still widely used.)
