A complementary razor holding structure is snugly inserted in to the side opening and has a V-shaped lower member having a rounded end portion, along which a number of grooves are provided. When the razor holding structure attached to a pair of razor blades is snugly inserted into the wide opening, a pair of gaps is formed between the razor blades and the V-shaped lower-member. Soapsuds are passed through the grooves and kept temporarily in the gaps, and the soapsuds are rinsed away in flowing water or liquid medicine. A correct angle of inclination of a line linking the lowest point on each respective razor blade and the lowest point on the rounded elongated lower member can be easily adjusted to between 20 and 30 degrees to fit the razor blades on the face of the skin for safe shaving of hair.
