Description

[Detailed description of the invention] The present invention has a thread 2 on the inner circumferential surface of a flat parallelogram-shaped tube body 1 made of a thin film such as polyethylene that covers a long sword body 3 having a parallelogram-shaped diagonal fold line 6. This is a simple cutter which is wound around the inner and outer picture bodies 3 and 1 in a diagonal spiral manner, and by unwinding and uncoiling the thread 2, a part of the covering 4 is cut off, allowing the blade part 5 to be freely exposed. , a safe and simple cutter is created by covering the long blade with a tube with thread, and when in use, the thread is unwound and released, a part of the covering is cut off, the blade is exposed, and the blade is broken off in sequence. The purpose is to expose the new blade part and use the remaining covered part as a handle or grip.

As shown in the figure, the break-off lines 6 are arranged obliquely on the three surfaces of the parallelogram-shaped long blade body, so that the scrap blade sections can also be appropriately broken off into the parallelogram shape.

In order to obtain the tightly fitted covering 4, the tube body 4 is heat-shrinked.

Since the present invention has the above-mentioned configuration, by covering the parallelogram-shaped long blade body 3 with the parallelogram-shaped flat tube body 1 with thread 2, a cutter that is safe and easy to use and handle can be easily manufactured. can be formed into

In addition, when in use, by pinching the tip of the thread 2 wound in a diagonal spiral shape around the inner peripheral surface of the tube body 1 with your fingertips and unwinding the thread, a part of the covering 4 is cut off. The portion 5 can be exposed and used for cutting.

After use, the used blade part is broken off along the diagonal break line 6, but since the cut end surface of the tube body 1 with a thin coating made by the thread 2 also remains obliquely, the used blade part is broken off one by one. It is convenient for exposing the new blade part.

There is also the advantage that the remaining coating can be used for the handle or grip of the blade.
