Abstract: Scissors were being used conveniently. However, according to the present invention, scissors are designed with the goal of improving cutting power, operability, and safety that requires further improvement. A method used to improve the cutting power rotates a scissor blade at a speed faster than that at which a material enters when rotating the scissor blade, to cut the material before pressing the material with pressure as in existing scissors, thereby improving the cutting power. The method further protrudes an edge portion of the rotating scissor blade toward a side thereof to contact another scissor blade, in order to minimize the contact area between the scissor blades. In terms of the operability, if users simply roll a roller over the material, the material is cut so that the cutting speed is fast. As the scissors have no need for an additional hand motion, the scissors can cut the material without misaligning the material, thereby being useful for precise cutting. In terms of the safety, the material can have the rounded scissor blade not exposed long and have a housing provided on the edge thereof to minimize the exposure of the scissor blade, thereby being advantageous for use as a work tool for children.
