PROBLEM TO BE SOLVED: To improving the sharpness of cutting of scissors, and to make the scissors more convenient by an intermediate blade body 8 stably held between main blade bodies 4 and 5 without shaking and by a so-called draw-cutting function. SOLUTION: Both main blade bodies 4 and 5 are supported rotatably in the opening/closing directions X of the main blade bodies 4 and 5 by a center axis 9 in a rotary supporting part 3, and an eccentric axis part 11 disposed in one main blade body 4 and an eccentric axis part disposed in the other main blade body 5 are disposed at eccentric positions relative to the center axis part 9. The intermediate blade body 8 has a guide hole to be relatively moved to the center axis part 9, a guide hole to be relatively moved to the eccentric axis part 11 of the one main blade body 4 and a guide hole to be relatively moved to the eccentric axis part of the other main blade body 5 when the main blade bodies 4 and 5 are opened/closed. The intermediate blade body 8 can be stopped and retained at the middle position of an opening angleθbetween the main blade bodies 4 and 5 when the main blade bodies 4 and 5 are opened/closed by the center axis part 9 and the respective eccentric axis parts and guide holes, and the intermediate blade body 8 can reciprocate in the longitudinal direction of the intermediate blade body 8 relative to the main blade bodies 4 and 5.
