The high and low grades of scissors depend largely on the fine workmanship. Observe the work one is to see the inner edge of the edge of the line that the edge of the inside a white light, for the scissors two blade contact track line is smooth, may open the scissors, then gently close, feel the shear mouth is smooth, the second is to see whether the guide rail is sleek, now most of the Scissors guide is "U" shape, Japanese scissors bias "V" shape, But the end must be sleek, the third is to see whether the handle conforms to ergonomic principles of design, scissors grip in the hands feel comfortable, finger in the circle will not have discomfort, refers to the edge of the circle is smooth and rounded, the end of the hand is solid, the tip is close.
