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 by house current. 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.
It was patented in 1928 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.
Some of the modern styles of electric hairclippers include the bulk hair clippers which are used to remove a bulk of the hair being shaved, the main hair clippers on which guards are attached to achieve a perfect length all over the head and the mini clippers which are used to trim the edges of the hair cut.
