Abstract
A safety razor which conforms to both concave and convex body surfaces and has a handle and a curved rotatable cartridge. Shaving blades are positioned on both sides of the curved cartridge, thus, both concave and convex accurate cutting edges are obtained in a single compact cartridge. The concave surface is used when shaving convex body surfaces. Rotating the cartridge 180 degrees exposes the convex cutting surface for shaving concave body surfaces. The cartridge is rotatably mounted to the handle and is held in either concave or convex shaving positions with detents. When the alternate shaving position is desired, the cartridge is rotated 180 degrees, either manually or remotely using a push button device within the handle, which is also disclosed. The correct angular relationship of the handle to the cutting surface of the cartridge is set and maintained for both concave and convex settings by means of the detents since the amount of rotation between the two shaving settings is 180 degrees.
