What is Razor?
A '''razor''' is a [[tool]], with one or more [[blade|blades,]] most commonly used by men for [[shaving]] the hair from their face, and by women for shaving hair from their legs and underarms. The earliest razors known are from the [[Bronze Age]]. They were made of [[bronze]] and had an [[oval]] shape. There are different kinds of razors today, including straight razors, which are rarely used, and safety razors and electric razors. A slightly different type of electric razor is used to trim and cut hair from the head, because hair can be cut much more quickly with electric haircutting razors than with scissors. ==Straight razors== [[Image:Rasiermesser.jpg|thumb|right|A straight razor]] Before the [[20th century]], straight razors were widely used. A straight razor consists of a [[knife]] blade, which can be reused. Since this blade is usually very sharp, there is a high risk of cutting oneself with the razor while scraping off the hair. Today, such razors are rarely used any more, except by barbers. ==Safety razors== In the late [[18th century]], [[French people|French]] engineer [[Jean-Jacques Perret]] invented the safety razor. With this system, the skin is protected, from all but the edge of the blade. This makes cutting much harder. The first such razor was released in [[1875]] by the [[Campfe Brothers]]. In [[1901]], [[King Camp Gillette]] invented the first razor with disposable razor blades. The blades were thrown away after several uses. The number of times a disposable blade can be used depends on beard coarseness and shaving technique, but the average is about one week. The company, [[Gilette]] still makes such razors today. They sell the razor relatively cheaply, and make big profits on the razor blades. ==Electric razors== ===For face and body hair=== [[Image:Philishave hq5426.jpg|thumb|right|A Philishave razor]] The electric razor was the next big step. With electric razors, [[shaving cream]], [[soap]] or [[water]] is no longer needed. Electric razors use electricity to either make blades [[rot
