Razor and its handle

A razor for shaving a skin surface, the razor comprising:

• a razor head including a side;
• a blade including a blade edge disposed along the side of the razor head;
• a handle having a front surface at the same side as the blade edge of the razor head, a rear surface opposite to the front surface, and a side surface between the front surface and the rear surface, in which a gripping section linearly extending in the range from the upper section of the side close to the blade edge up to the lower section of the side far from the blade edge are formed on the handle, wherein:
• the entire length along the longitudinal direction of the gripping section and including the razor head and the handle is L, and L satisfies the relation of 108 mm≦L≦138 mm,
• the entire width between both ends of the razor head in the cross direction of the blade edge is W, and W satisfies the relation of 34 mm≦W≦44 mm,
• the angle formed between the shaving tangential plane on the razor head when applying the razor head to a skin surface together with the blade edge and a plane including the center line in the longitudinal direction of the gripping section of the handle is θ, and θ satisfies the relation of 11°≦θ≦33°,
• the maximum distance in the cross direction between the front surface and the rear surface of two directions orthogonal to each other on a cross section orthogonal to the longitudinal direction of the gripping section of the handle is DX, and the maximum distance in the cross direction between both side surfaces is DY, DX satisfies the relation of 9.5 mm≦DX≦13.5 mm and DY satisfies the relation of 9 mm≦DY≦13 mm, and
• the whole mass including the razor head and the handle is M, and M satisfies the relation of 8.5 g≦M≦11.5 g.
