A top portion extends from an upper end of a handle. The top portion is curved from the front to the back. A clearance is located between the back side of the razor head and the front of the top portion of the holder. The clearance between the back side of the razor head and the front of the top portion is changed by means of a pivoting mechanism such that, when the razor head is at the neutral position, the clearance at a position separated from the cutting edge is greater than the clearance at a position in the vicinity of the cutting edge. When the razor head is moved from the neutral position to a specified movement position, the clearance at the position separated from the cutting edge is less than the clearance at a position in the vicinity of the cutting edge.
