置面２，１１の境は段差をなす。Embodiments of the present invention will now be described with reference to the drawings. The tool rest 1 is formed of plastic integrally with the handle 16. The two blade mounting surfaces 2 and 11 are formed on the upper surface of the blade base 1 in parallel with the longitudinal center line of the blade base 1 as a boundary. Both the blade mounting surfaces 2 and 11 are inclined surfaces that rise upward. Therefore, the boundary between the two blade mounting surfaces 2 and 11 forms a step.

An elongated whiskers discharge hole 5 is provided along the front edge of the blade stand 1 in the front portion of the leading blade mounting surface 2. A front portion of the whiskers discharge hole of the leading blade 3 becomes a guard portion 17 extending in the longitudinal direction. Each of the whiskers discharge holes 5 and 6 is provided with three reinforcing ribs 18 and 19.

And the top plate 20 is attached to the blade stand 1. The top plate 20 is composed of both side plate portions 23, 23 and two parallel blade holding portions 12, 13 connecting between the both side plate portions. The two blade holding portions 12, 13 are the leading blade 3 and the trailing blade. It serves to fix the blade 4 on the blade mounting surface. The rear upper surface of the leading blade holding portion 12 becomes the guard portion 24 of the trailing blade 4.

The tips of the comb teeth 9 and 10 have just reached the blade edges 14 and 15 of the double blades 3 and 4. However, comb teeth 9 and 10
The position of the tip of is not limited to this embodiment, and may be slightly beyond the blade edge or slightly before the blade edge.

果を奏する。The present invention is constructed as described above, and by providing the grooves 7 and 8 of which the depth is gradually increased from the upper surfaces of the double-edged clamping portions 12 and 13 toward the front, the blade clamping is achieved. The front edges of the attachment parts 12 and 13 are formed in the shape of comb teeth, and each comb tooth 9,
The tip of 10 reaches near the edges of both blades 3 and 4. Therefore, since the comb teeth 9 and 10 have the same effect as when the two blade edges 14 and 15 are covered at regular intervals, the safety of the two-blade safety razor can be enhanced. There is also a means for providing a projection on the front upper surfaces of the blade gripping portions 12 and 13 in order to achieve the same covering action. Since they are added, there is a drawback in that the protrusion hits the skin strongly and the skin feels bad. On the other hand, in the present invention, the comb teeth 9 and 10 are formed by providing the grooves 7 and 8 of which the depth gradually increases from the upper surface of the blade holding portions 12 and 13 toward the front. Therefore, the comb teeth that cover the blade edge need only be as thick as the thickness of the blade clasp portion, so that the skin feels good during use.
