The present invention is intended to be faster, more accurate, and more convenient in processing paper and acquiring important information and materials for media such as newspapers and magazines.

In modern society, most documents are computerized. However, in magazines, newspapers or professional books, there are still a large number of paper-based media published, and scraps are used to capture materials and information in these media. Scrap is a method of selecting and sorting only the information you need, most of which uses scissors or knives. There is a disadvantage in that it is not possible to precisely cut a straight line in acquiring data using scissors, and a disadvantage is that it is impossible to accurately cut a curve in using a knife. The present invention has been devised to solve each of these problems at once.

Knife that can cut the curve freely and conveniently with the straight line and the curve of the picture and the figure, including the supporting part, the tip part, the axis of rotation, and the cutting guide point.

If the cutting edge of the tip becomes dull due to the large amount of paper cut, the knife that can cut the curve can be used as it is the same size as the refilling blade on the market.

Cutter knife, which is sold or most commonly used in the market, can only be cut in a straight line, so when cutting a curved picture or picture, it has to be cut by turning the wrist or rotating paper and cannot cut precisely. There was discomfort. However, the present invention can be said to be more original and superior than the conventional products because it can give a comfortable free curve cutting and wrist comfort as if grabbing a pen due to the rotation of the tip portion.

It is possible to solve the inconvenience of carrying scissors and cutter knife together, and it is used in the form of a pen that is very familiar by using a lot of existing ones. It is also convenient to carry and more practical.

It is possible to cut straight line and curved line, so it can do both functions of knife and scissors at the same time. If the cutting edge of the paper is blunt because the amount of paper cutting is large, it can be replaced with the same size as the refilling blade currently on the market. It can be called economic.

In the case of the present invention can be divided into two parts, the front end portion 50 that the blade is embedded and the support portion 20 that can be used by hand. In the case of the blade 10 embedded in the tip portion 50, there are very few exposed parts to the outside, so there is almost no risk of injury when using the blade 10, and the blade 10 can be cut along the boundary of the picture or photo. The cutting guide pointer 40 is displayed toward the side and includes a rotating shaft 30 so that the curve can be freely rotated and cut. The tip portion 50 includes a rotating shaft 30, so that when cutting the curve with a conventional cutter knife while cutting the wrist in an uncomfortable posture while turning the wrist or turning the paper, the present invention is cut while flipping the wrist in the form of holding a pen Various curves can be cut without inconvenience. In addition, the front end portion 50 can be said to be more convenient because the sides are fixed to both sides so as not to push or deviate paper.
