ABSTRACT:

BACKGROUND OF THE INVENTION
1) Field of the Invention
The invention is related to a kind of scissors which is applicable in cutting paper and cloths.
2) Description of the Prior Art
As known, a scissors is a cutting implement having two blades joined by a pin that allows the cutting edges to be opened and closed. Normally, a scissors is used to cut a paper in one direction. Once diversified cutting direction is desired, such as 90 degrees, one has to rotate the paper or change the cutting direction, which is very difficult when the paper is very large or heavy. Also, constant paper cutting is very difficult.
SUMMARY OF THE INVENTION
The invention is a scissors, which is applicable for paper cutting at various directions without any difficulty. To achieve the above objective, the invention includes two cutting implements joined by a pin, which allows the blades and handles of the cutting implements to move. In the design of the invention, a cutting implement includes a blade and handle. The cutting implements are joined by a pin disposed between the blades and handles. With the particular design, the cutting implement allows one to cut along a curved path on a first plane, which is orthogonal to a second plane formed by operating the cutting implement. With the invention, a curved cutting path is reached.
One of the best embodiments of the invention is the application of a cutting implement, which includes a blade and flexible handle. By the joint of the flexible blades, an object in a different form of cutting implement is developed. When an angle desired is reached, it may join the blades to form a constraint mechanism.
Another embodiment of the invention is the application of a cutting implement, which includes a blade and handle. By the joint of flexible blades, a constraint mechanism functions on the basis of gearinlay on blades.
Another embodiment of the invention is the application of a cutting implement, which is located between a pin and handles. By the joint of flexible blades, a constraint mechanism functions on the basis of gear inlay on blades.
