Technology is one aspect of being a human being that sets us apart from all other living animals on this planet. When compared to an animal, such as a dog or a cat, humans have access to far larger brains, our thumbs, computers, and even the dishwasher. With such impressive technologies, humans have become the dominant species on the planet. Unfortunately, not all technology is available to everyone in our society, though. Some items have been deemed classified or for military use only by various governments. Here are ten incredible technologies you can never use.

Damascus Steel

Damascus Steel is the impressive material used during the Middle Ages to craft swords and other weapons. Today, however, the exact process is somewhat hidden and the recipe is gone entirely.

Vitrum Flexile

Vitrum Flexile is a type of flexible glass that is stronger than normal glass. When thrown on the ground, it simply bends instead of shatters. Emperor Tiberius, however, feared the invention, so he killed the glassmaker behind it and burned his shop to the ground.
