    Abstract: Left and right blades (4, 5) of children's scissors (1) are metal plates of a substantially constant thickness in their entirety. Outer peripheral end surfaces (4b, 5b) of distal end parts (4a, 5a) of the blades (4, 5) are end surfaces of a fixed width in which one end is uninterruptedly connected to distal ends (2a, 3a) of cutting blades (2, 3). A contour form of the outer peripheral end surfaces (4b, 5b) is defined by convex curves (C1, C2). The distal end parts (4a, 5a) of the blades (4, 5) form a heart-shaped contour form C in a state in which the blades (4, 5) are closed and the cutting blades (2, 3) are brought together. Even while the children's scissors (1) are open, there is no danger of an injury being caused by a sharp corner of the cutting blades becoming exposed and a finger tip or other body part coming into contact with the cutting blades, which is a problem in conventional scissors, and safety is achieved.
