However, it is inconvenient because it is necessary to use an underlay for a cutter because it may damage the lower surface of the paper or the tabletop. There is an improvement plan (Actual Kaihei 5-26071). However, in this invention, the cutter knife protrudes from the tip of the holder, and when used, it damages the lower part of the cut paper surface like the conventional cutter knife.

出来る。The paper 10 to be cut or cut out is slidably fitted between the L-shaped projection 3 and the tooth tip 7 of the blade 4 of the cutter knife 1,
Move the cutter knife in the direction of the addendum to cut or cut out paper. In particular, in the case of cutting out, first, a slit is made on the paper surface by about 5 mm with a normal cutter knife, and the L-shaped projection 3 is pierced through the opening in the lower portion of the paper surface and cut. The cutting is a tooth tip 7
Although the force for escaping from it acts downward, the tooth tip 7 of the cutter knife comes close to the groove 6 formed in the L-shaped projection 3 and pushes it downward, facilitating the cutting of thin paper and the like. When the thickness of the paper to be cut is different, it can be adjusted by taking in and out the blade 4.

In the cutter knife 1 having the blade 4 provided therein, the L-shaped projection 3 is tacked to the tip of the grip 2 through the hole 5 and is rotated to the locking dowel 9 provided on the grip 2 when in use. A groove 6 is formed at the tip of the L-shaped projection 3, the blade 4 of the cutter knife is brought close to the paper, and the paper 10 to be cut is slightly inserted.
The paper or the like to be cut is cut by the shearing force of the tooth tips 7 of the cutter knife. At the same time, the force of the cut object to escape from the tooth tips 7 acts downward, but the blade 4 is inserted into the groove 6 installed in the L-shaped projection 3. The tooth tips 7 are close to each other, and it becomes easy to cut thin paper or the like. The same effect can be obtained even if the tip of the L-shaped projection 3 is V-shaped. FIG. 3 shows another embodiment of the present invention, in which an L-shaped projection 3 is tacked to a metal sheath 8 and is rotated forward of a blade 4 for use in cutting and cutting. Further, it can be used as a normal cutter knife by causing the L-shaped projection 3.

If the cutter knife of the present invention is used, cutting and cutting can be performed without using an underlay, and the L-shaped projection 3
By rotating the, you can get the convenience of using it as a normal cutter knife. Further, the thickness of the paper to be cut and cut out can be adjusted by moving the blade 4 of the cutter knife up and down.
