In this study, a scissors with equal displacement between pushing handles and cutting blades was proposed. The proposed scissors comprises six parts. The six parts are upper and lower handle parts, upper and lower link parts, and upper and lower blade parts. The proposed scissors is cam and link mechanisms. Specific design methods were showed from the mechanisms. In the design methods, angles of the lower blade part were gotten from relationship between positions of the lower blade, and intersections of the upper and lower blades. Pushing displacement at connections between the handles and frames is equal to cutting displacement at the intersections. Relationship between the angles of the lower blade part, and angles of the upper handle part was gotten. Positions of an upper cam such that relationship of gotten two angles was gotten.
