ABSTRACT:
The scissors for household and medical use comprise an upper and lower blade defining a distal region and an upper and lower handle defining a proximal region. The lower blade and handle are formed as one piece and the upper blade and handle are formed as two separate pieces. The upper blade is movably linked to the lower blade by means of a mechanism--e.g. a four-bar linkage--allowing to move said upper blade by acting on said upper handle leaving said one-piece lower blade and handle stationary.
