Preferably, the first edge and the second edge are both of a single curvature, and the first edge and the second edge have the same radius of curvature.

Preferably, the angle of the first edge angle is 23 to 27 degrees.

By utilizing the technical characteristics, the curve scissors have the following efficacy improvements:

1. because the first edge of the first blade part and the second edge of the second blade part are curved, even when the front ends of the first blade part and the second blade part are used for cutting, a larger opening angle can be maintained between the first blade part and the second blade part, so that the cutting is convenient for a user to apply force.

2. The angle of the second blade angle is larger, the second blade angle can be used as a static blade of a pair of scissors, the first blade angle is smaller and sharper when cutting objects, and the second blade angle can be used as a movable blade of the pair of scissors to provide better cutting force, so that when the first blade body and the second blade body are relatively closed to cut the objects, the cutting stability can be improved, a user can apply force better, when the objects with thinner cutting thickness are cut, the displacement of the objects can be avoided, and the objects are cut more easily.
