ABSTRACT:
A shaving apparatus is described that has a handle, a bifurcated expansion means with one end connected to the handle and with another end attached to a razor head containing at least one blade and at least one spacer that are retained in a base in such a manner so as to allow the blades and spacers to move longitudinally as the base, blades and spacers are moved from a convex curve through a straight configuration to a concave curve to accommodate the various surfaces requiring shaving on the body. There is an adjustment means on the apparatus that allows the user to select the curvature of the blade desired without visually referencing the apparatus. There is a contraction means to enhance the movement of the blades from the expanded position of the concave configuration to the retracted position of the convex configuration.
