A razor is a bladed tool primarily used in the removal of unwanted body hair through the act of shaving.[1] Kinds of razors include straight razors, disposable razors, and electric razors.While the razor has been in existence since before the Bronze Age (the oldest razor-like object has been dated to 18,000 BC[2]), the most common types of razors in current usage are the safety razor and the electric razor, though other kinds are still in use. A blade is the portion of a tool, weapon, or machine with an edge that is designed to puncture, chop, slice or scrape surfaces or materials. Blades are typically made from materials that are harder than those they are to be used on. Historically, humans have made blades from flaking stones such as flint or obsidian, and from various metal such as copper, bronze and iron. Modern blades are often made of steel or ceramic. Blades are one of humanity's oldest tools, and continue to be used for combat, food preparation, and other purposes.
Blades work by concentrating force on the cutting edge. Certain blades, such as those used on bread knives or saws, are serrated, further concentrating force on the point of each tooth.
