In lower-quality scissors, the cutting edges are not particularly sharp; it is primarily the shearing<span> action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp, and tension sprung - to increase the cutting and shearing tension only at the exact point where the blades meet. The hand movement (pushing with the thumb, pulling with the fingers) can add to this tension.
