  • Patent number: 7827695
    Abstract: This new electric razor has a set of multiple shaving knives (12), having dual cutting edges longitudinally on both sides of knife, and rotating and reciprocating simultaneously on the inner surface of a cylindrical shaving screen (11). This mechanism creates a 3-dimensionally elliptical motion of the shaving knives that effectively slices hair off (not chopping) and provides a smooth and comfortable shave with minimum skin irritation. The cylindrical shaving screen (11) and the main body (19) containing a rotating cup (16), a motor (17) and power source (18) forms an inherently ergonomic, angled shape, which is also slim and compact overall for convenient use and easy carrying. This razor has a 360 degree effective shaving screen surface and can be used in wet or dry environments. Cleaning the shaving head screen requires no disassembly and can be done easily under running water.
