Manual safety straight razor having doubled-sided blades

A manual safety straight razor having doubled-sided blades which comprises:

• an elongated front cutter portion having a dog-deformed rear handle portion which is pivotally and rotationally secured to a rear portion of said elongated front cutter portion, said dog-deformed rear handle portion having a pair of dog-deformed plates which are joined together by a bolt, nut, washers and a ring;
• said elongated front cutter portion having a longitudinal cutter head portion, an elongated wide opening, a pair of first exposed surfaces which are slightly, downwardly narrowed, and a pair of second exposed surfaces' which are further narrowed and curved into a pair of narrow wedge portions which are spaced from each other to form a narrow wedge portion;
• a complementary razor holding structure which includes a pair of first slightly, downwardly narrowed surfaces corresponding to the inner faces of said elongated wide opening, a pair of longitudinal grooves, a plurality of projections provided longitudinally with a given interval and a V-shaped lower member having a rounded end portion which are brought into contact with the inner faces of said elongated wide opening, and said V-shaped lower member having a number of parallel grooves along said rounded end and curved into a narrow wedge portions which are spaced from each other to form a wedge portion;
• a pair of razor blades attached on either side face of said complementary razor holding structure, each blade having a plurality of grooves provided longitudinally to correspond to the projections of said projections of the complementary razor holding structure;
• which is characterized in that when the complementary razor holding structure attached with a pair of said razor blades is snugly inserted into the elongated wide opening, a pair of gaps are formed into between the razor blades and the V-shaped lower member to form an imaginary V-shaped working plane formed by a pair of two imaginary lines.
