Not only did they build the pyramids, but the ancient Egyptians also developed some of the earliest examples of shaving tools and did quite a bit of experimentation with various blade materials. The flint blades they first used ultimately gave way to copper and bronze blades, some of which have been found in Egyptian tombs. Aristocratic men in the Egyptian dynasties of 7,000 years ago not only shaved their faces, but also their heads and bodies for a more fashionable look and as a defence mechanism in battle. The Egyptians also shaved to keep cool in a hot climate and to avoid lice infestations. Who knew shaving was so good for you?
