[编辑] 早期剃刀
In its simplest form, a razor is a steel blade attached to a handle. Razors have been identified from Bronze Age Britain. These are made of bronze, generally oval in shape with a small tang protruding from one of the short ends.
Straight razors (also called cut-throat razors) with open steel blades were the most common before the 20th century—and, in many countries, until the 1950s. They are now used chiefly by barbers.
[编辑] 安全剃刀（亦称刮胡刀）
The safety razor was developed in the mid-1800s. Early razor blades needed continuous sharpening, soon becoming worn out, making them expensive. The Kampfe Brothers developed a type of razor along these lines. The safety razor first developed in the United States by the Kampfe Brothers used a forged blade.
In 1903, the American inventor King Camp Gillette invented a safety razor with disposable blades. Gillette realized that a profit could be made by selling a safety razor at a reduced price and then making a nice profit margin on the inexpensive disposable blades. This has been called the Razor and blades business model, or a "loss leader". To realize his idea, Gillette founded the American Safety Razor Company on September 28, 1901. The company's name was changed in July 1902 to Gillette Safety Razor Company. Gillette's particular innovation for disposable safety razors (patent US775134) beat out competitors.
Gillette's thin blade was covered by the razor, thus protecting the skin against deep cuts. This enabled people to safely shave themselves for the first time. Plastic disposable razors and razors with replaceable blades, often with two or three cutting edges (but sometimes with four and soon five cutting edges), are in common use today.
[编辑] Electric razor
The electric razor (also known as the electric dry shaver) is a common electrical shaving device with a rotating or oscillating blade. The electric razor does not require the use of shaving cream, soap, or water. The razor is powered by a small DC motor, and usually has rechargeable batteries, though early ones were powered directly from the mains.
It was invented in the 1930s by the American manufacturer Col. Jacob Schick. The Remington Rand Corporation developed the electric razor further, first producing the Remington brand of razor in 1937. Another important inventor was Prof. Alexandre Horowitz, from Philips Laboratories in the Netherlands, who invented the very successful concept of the revolving electric razor. It has a shaving head consisting of cutters that cut off the hair entering the head of the razor at skin level.
Early versions of electric razors were meant to be used on dry skin only. More recent electric razors have been designed which allow for shaving cream and moisture.

[编辑] Other razors
A utility knife is a common tool used in grocery stores and other places. Such a knife generally consists of a simple and cheap holder, typically flat, approximately one inch wide and three to four inches long, and typically made of either metal or plastic. Some use standard razor blades, others specialised double ended blades.
A potato peeler is a metal blade attached to a metal, plastic or wooden handle that is used for peeling vegetables, usually potatoes.
Razor wire is a mesh of metal strips with sharp edges whose purpose it is to prevent passage by human beings. Furthermore, razor wire is sharper than the barbs of barbed wire.
