To solve problems wherein, when ceramic is used for blade bodies of scissors, a shearing stress of the scissors is concentrated in a rotational fulcrum part; when fixing them with a metal screw, the hardness of the ceramic is harder than that, so that the metal screw is abraded, causes rattling and affects the service life of the scissors; and rust is developed by the abrasion of the metal screw, becoming stuck to the ceramic blade bodies and giving adverse effects to its aesthetic appearance and the retention of sanitation.
The scissors 1 are provided with a rotational fulcrum part 2 rotationally journaling one-side blade body 1A and the other-side blade body 1B, wherein the one-side blade body 1A and the other-side blade body 1B are formed of Ti alloy or ceramic sintered body, through-holes 1Aa and 1Ba are bored in the rotation fulcrum part 2, a ceramic ring 2a is rotationally inserted into the through-holes 1Aa and 1Ba, a fixing shaft 2b is penetratingly fixed to the ceramic ring 21, and the ceramic ring 2a contains CuO.
