PROBLEM TO BE SOLVED: To maintain the sharpness of scissors so as to be used for a long time which have become dull and required patience or the purchase of a new one before. SOLUTION: A yoke 2 is mounted to a pair of a scissors main body 1, and a magnet 3 is mounted to the yoke 2. A blade 4 is attached to the yoke 2 by the magnetic force of the magnet 3.
