A razor refers to a bladed tool primarily used to remove undesirable hair on the body, shaving. Razors existed in many cultures in the ancient world before the Bronze Age. In Bronze cultures, this tool was made using obsidian or bronze. They were had an oval shape, with the short end having a small tang protruding. The modern razors were invented in the 18th century and the 1960s saw the invention of the electric razors.
Technology has evolved how these products are made. The market today has a huge variety of cheap razor blades to choose from. Straight razors, disposable razors, and electric razors are examples of razors on the market. Each variety was invented at a different time.
In years before the 20th century, straight razors were the commonest kinds of razors in existence. They are also called cut-throats. They are made of handles, which have one sharpened edge. Two major kinds of materials are used to make them, that is, carbon steel and stainless steel. Stainless steel strops and hones slowly and holds edges longer. On the contrary, carbon steel have less durable edges and they strop and hone faster.
Both stainless and carbon steel razors continue to be manufactured even today. However, those made of stainless steel are rarer. Cut-throats razors revolve between protective scales on pins. The purpose of the scales is protecting skins from being cut and the blade from be damaged when one folds the tool. Bone, mother-of-pearl, wood, celluloid, plastic, and ivory are some of the materials used to make handle scales. However, ivory is no longer used.
Disposable blade straight razors are similar to straight razor in their use and appearance. However, they use disposable blade, which may be single-edged or double-edged blades cut into half. These variants also do not need stropping and honing. The razors also wear out faster, but the useful blade life can be made to last longer through proper care. Care usually include drying the blade thoroughly after use.
Safety razors are designed to protect the skin from cuts from all parts of the equipment, but the edge. Jean-Jacques Perret is credited with inventing it in 1762. Safety razors have similar designs as straight razors, with the difference being that their blade is enclosed in sleeves. The skin is protected by safety bars in modern varieties. Double-edged and single-edged models are the two types of safety blade in existence.
Electric dry shaver is the other name for electric razors. They have a blade that rotates when they are working. DC motors are the main sources of power. The DC motors derive power from mains electricity or rechargeable or maintenance free batteries. Electric razors are more convenient because one does not need water, shaving cream, or soap to use them.
Invention has led to the development of new electric razors that rely on rechargeable batteries for power. Rechargeable batteries may be alternated with electro-mechanical oscillators that are driven by AC-energized solenoids. The oldest models of electric razors were powered by hand. Flywheels in the devices were driven by pulling a cord by hand.
