History
Razors have been identified from many Bronze Age cultures. These were made of bronze or obsidian and were generally oval in shape, with a small tang protruding from one of the short ends.[citation needed]
Various forms of razors were used throughout history, which are different in appearance but similar in use to modern straight razors. In prehistoric times clam shells, shark's teeth, and flint were sharpened and used to shave with. Drawings of such blades were found in prehistoric caves. Some tribes still use blades made of flint to this day. Excavations in Egypt have unearthed solid gold and copper razors in tombs dating back to the 4th millennium BCE. The Roman historian Livy reported that the razor was introduced in ancient Rome in the 6th century BCE. by legendary king Lucius Tarquinius Priscus. Priscus was ahead of his time because razors did not come to general use until a century later.[1]
