ABSTRACT:
This invention relates to a pair of handy scissors for readily cutting paper, cloth, thread, synthetic resin films and other sheet-like or linear materials in doing paper craftwork or needlework or opening packing bags. The scissors are constructed in the following manner: A parting line of predetermined length is cut in a springy metal sheet of uniform thickness to form cut edges in the form of cut surfaces each crossing the planar surface of the metal sheet at an acute angle, the cut edges as such serving as a pair of cutting edges for shearing an object, the half portions of the metal sheet bisected by the cutting of the parting line being bent in vertically opposite directions along a pair of bending lines on the planar surface so that they are normally in a horizontally V-shaped opened state and are in such a relation as to cross the parting line at an obtuse angle, while a pair of opposed operating levers are attached to the half portions for closing the half portions against the spring force of the metal sheet so as to shear an object by the mutual rubbing action of the cutting edges.
