Electric razors




The electric razor (also known as the electric dry shaver) has a rotating or oscillating blade. The electric razor usually does not require the use of shaving cream, soap, or water. The razor may be powered by a small DC motor, which is either powered by batteries or mains electricity. Many modern ones are powered using rechargeable batteries. Alternatively, an electro-mechanical oscillator driven by an AC-energized solenoid may be used. Some very early mechanical shavers had no electric motor and had to be powered by hand, for example by pulling a cord to drive a flywheel.

The first electric razor was invented by John F. O’Rourke in 1898. Industrial production of electric razor machines started in 1937 by the US company Remington Rand based on the patent of Jacob Schick from 1928. Since 1939 the Dutch company Philips has produced electric razor machines. One of the main differences between electric razors is the shaving technology they use. Usually electric shaving machines use several round rotating shaving blades or a horizontally shaver’s foil and cutter block technology.

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 BC.

A razor is a bladed tool primarily used in the removal of body hair through the act of shaving. Kinds of razors include straight razors, safety razors, disposable razors, and electric razors.
